This article aims to develop an accurate and efficient meshfree Galerkin method based on the strain smoothing technique for linear elastic continuous and fracture problems.

This paper proposed a generalized linear smoothed meshfree method (LSMM), in which the compatible strain is reconstructed by the linear smoothed strains. Based on the idea of the weighted residual method and employing three linearly independent weight functions, the linear smoothed strains can be created easily in a smoothing domain. Using various types of basic functions, LSMM can solve the linear elastic continuous and fracture problems in a unified way.

On the one hand, the LSMM inherits the properties of high efficiency and stability from the stabilized conforming nodal integration (SCNI). On the other hand, the LSMM is more accurate than the SCNI, because it can produce continuous strains instead of the piece-wise strains obtained by SCNI. Those excellent performances ensure that the LSMM has the capability to precisely track the crack propagation problems. Several numerical examples are investigated to verify the accurate, convergence rate and robustness of the present LSMM.

This study provides an accurate and efficient meshfree method for simulating crack growth.

Increasingly, leaders are faced with complex, difficult and demanding situations that challenge their very sense of self, including their workplace wellbeing. It has been suggested that this challenge can be mitigated for leaders by pursuing goals and activities that reflect their beliefs, interests and values. As such, leaders whose motivations reflect intrinsic and self-congruent beliefs and values are likely to experience beneficial wellbeing, yet, reviewing this from a self-determination theory (SDT) lens, the authors find this assertion remains to be fully tested. Concurrently, the work–family enrichment (WFE) literature highlights that potential positive synergies exist between work and home. The authors further argue that this synergy may also provide greater insight and understanding into the quality of leaders’ motivation and wellbeing, and as such also requires attention. As such, the purpose of this paper is to examine the path to wellbeing for leaders and includes leaders’ “whole lives” (including enrichment) and not just their work lives (motivations).

Quantitative research including two studies of 386 junior/senior leaders and 205 CEOs, investigated the role of motivation as defined by SDT and WFE towards leaders’ job satisfaction. Hypotheses were tested using SEM in AMOS to assess the direct and meditational effects of the study variables.

A partial mediation model was found to best fit the data for both studies. In study 1, the effects of self-determined motivation dimensions on job satisfaction were fully mediated by WFE and family–work enrichment (FWE). However, the non-self-determined dimensions of SDT motivations were directly and negatively related to job satisfaction and enrichment. In study 2, self-determined forms of motivation were positively related to WFE and FWE and job satisfaction, while only WFE was positively related to job satisfaction. The non-self-determined dimensions of SDT motivations were directly and negatively related to WFE and job satisfaction.

Overall, both studies show that the influence of motivations on job satisfaction of leaders is better understood through enrichment. As such organisations are encouraged to enhance both leader’s motivations, and enrichment, in order to facilitate a path to job satisfaction.

This paper is the first to test over two studies and levels of leadership, motivation and enrichment for leaders. As such this paper provides a novel “path” to wellbeing that includes aspects of the leaders’ motivation, as well as the importance of leaders’ enrichment and home domain. Overall the authors suggest that leaders’ “whole” lives play a role in their job satisfaction, and this is important to understand as the authors try to resource leaders, who work in an increasingly demanding workplace environment.

The purpose of this paper is to examine the role of job crafting behaviors in predicting work-family enrichment. It is hypothesized that employees who are able to adjust their work environment proactively by increasing structural and social job resources, increasing challenging job demands and decreasing hindering job demands would be more engaged and experience work-family enrichment.

The sample for the study consisted of 496 employees working in diverse nature of organizations in India. Structural equation modeling with the help of SPSS AMOS 20 was used for testing the study hypotheses.

The results reveal a strong relationship between job crafting and work-family enrichment experiences among employees. The study also established the role of work engagement as a mediator of the relationship between job crafting and work-family enrichment.

The study significantly advances the underdeveloped literature on work-family enrichment by establishing job crafting as a predictor and illuminating the underlying psychological processes in a non-western collectivist culture. The study also contributes to theory building around the construct of job crafting which is still in its infancy.

The practitioners are encouraged to provide opportunities, support and freedom for job crafting to their employees for better work and home outcomes.

The present study is one of the pioneer attempts to examine how employees themselves can influence work-family enrichment by enhancing their work engagement using job crafting.

The purpose of this paper is to propose a new elemental enrichment technique to improve the accuracy of the simulations of thermal problems containing weak discontinuities.

The enrichment is introduced in the elements cut by the materials interface by means of adding additional shape functions. The weak form of the problem is obtained using Galerkin approach and subsequently integrating the diffusion term by parts. To enforce the continuity of the fluxes in the “cut” elements, a contour integral must be added. These contour integrals named here the “inter-elemental heat fluxes” are usually neglected in the existing enrichment approaches. The proposed approach takes these fluxes into account.

It has been shown that the inter-elemental heat fluxes cannot be generally neglected and must be included. The corresponding method can be easily implemented in any existing finite element method (FEM) code, as the new degrees of freedom corresponding to the enrichment are local to the elements. This allows for their static condensation, thus not affecting the size and structure of the global system of governing equations. The resulting elements have exactly the same number of unknowns as the non-enriched finite element (FE).

It is the first work where the necessity of including inter-elemental heat fluxes has been demonstrated. Moreover, numerical tests solved have proven the importance of these findings. It has been shown that the proposed enrichment leads to an improved accuracy in comparison with the former approaches where inter-elemental heat fluxes were neglected.

The purpose of this paper is devoted to present an accurate assessment for determine natural frequencies for uniform and non-uniform Euler-Bernoulli beams and frames by an adaptive generalized finite element method (GFEM). The present paper concentrates on developing the C1 element of the adaptive GFEM for vibration analysis of Euler-Bernoulli beams and frames.

The variational problem of free vibration is formulated and the main aspects of the adaptive GFEM are presented and discussed. The efficiency and convergence of the proposed method in vibration analysis of uniform and non-uniform Euler-Bernoulli beams are checked. The application of this technique in a frame is also presented.

The present paper concentrates on developing the C1 element of the adaptive GFEM for vibration analysis of Euler-Bernoulli beams and frames. The GFEM, which was conceived on the basis of the partition of unity method, allows the inclusion of enrichment functions that contain a priori knowledge about the fundamental solution of the governing differential equation. The proposed enrichment functions are dependent on the geometric and mechanical properties of the element. This approach converges very fast and is able to approximate the frequency related to any vibration mode.

The main contribution of the present study consisted in proposing an adaptive GFEM for vibration analysis of Euler-Bernoulli uniform and non-uniform beams and frames. The GFEM results were compared with those obtained by the h and p-versions of FEM and the c-version of the CEM. The adaptive GFEM has shown to be efficient in the vibration analysis of beams and has indicated that it can be applied even for a coarse discretization scheme in complex practical problems.

The purpose of this paper is to evaluate the capabilities of the generalized finite element method (GFEM) under the context of the geometrically nonlinear analysis. The effect of large displacements and deformations, typical of such analysis, induces a significant distortion of the element mesh, penalizing the quality of the standard finite element method approximation. The main concern here is to identify how the enrichment strategy from GFEM, that usually makes this method less susceptible to the mesh distortion, may be used under the total and updated Lagrangian formulations.

An existing computational environment that allows linear and nonlinear analysis, has been used to implement the analysis with geometric nonlinearity by GFEM, using different polynomial enrichments.

The geometrically nonlinear analysis using total and updated Lagrangian formulations are considered in GFEM. Classical problems are numerically simulated and the accuracy and robustness of the GFEM are highlighted.

This study shows a novel study about GFEM analysis using a complete polynomial space to enrich the approximation of the geometrically nonlinear analysis adopting the total and updated Lagrangian formulations. This strategy guarantees the good precision of the analysis for higher level of mesh distortion in the case of the total Lagrangian formulation. On the other hand, in the updated Lagrangian approach, the need of updating the degrees of freedom during the incremental and iterative solution are for the first time identified and discussed here.

The purpose of this paper is to examine core self‐evaluations (CSEs), family support, co‐worker support, supervisor support, job characteristics, work‐life balance policies (WLBPs) and work‐family culture as the predictors of work‐to‐family enrichment (WFE) and family‐to‐work enrichment (FWE) and explore the moderating effect of CSEs.

Data were collected through a questionnaire survey from 485 employees from six organizations in India representing manufacturing, telecommunications and information technology sectors and were analyzed using hierarchical multiple regressions.

Supervisor support, job characteristics, WLBPs and work‐family culture predicted WFE. CSEs, family support and job characteristics predicted FWE. Little moderating influence of CSEs was found. It moderated the relationship between supervisor support and WFE.

The cross‐sectional design of the study constrains inferring conclusions regarding causality.

This study indicates that from an organizational perspective, involvement in family roles should not be viewed as a hindrance, since it can also benefit employees at work. Employee assistance programs may be introduced to help employees develop the necessary skills and adaptability to increase their work‐family enrichment experience.

The construct work‐family enrichment examined in this paper reflects an understanding of work‐family interface from a newer lens in a novel socio‐cultural context and demonstrates the moderating role of CSEs.

This study examines the role of Saudi women’s work motivational drivers on work–home conflict (WHC) and work–home enrichment (WHE). It considers the moderating role of psychological detachment from work during the evening between one workday and the next and how it impacts on the mediating role of WHC and WHE on work performance.

Drawing on self-determination theory and enrichment and depletion perspectives on the work–home interface, the study employs a quantitative lagged study over a period of three consecutive working days, with data collected from 358 Saudi women working in academia.

Moderated mediation structural equation modelling (MMSEM) analysis reveals that intrinsic motivation is significantly, positively related to WHE and home–work enrichment (HWE), whereas extrinsic motivation is only significantly and positively related to home–work conflict (HWC). Results show that detaching from work weakens the positive association between intrinsic motivation and HWE. In line with predictions, WHE is significantly, positively related to citizenship behaviour towards both individuals and organizations, whilst HWE is significantly related to citizenship behaviour towards individuals only. HWC is only significantly related to citizenship behaviour towards the organisation.

The research highlights the enriching experiences for Saudi women, who have the opportunity to pursue a career and highlight benefits of their ongoing empowerment.

This research brings a unique motivational perspective to work–life research and addresses a shortcoming of work–life research in considering an understudied culturally distinct population. It emphasises on the enriching experiences of Saudi women who have the opportunity to pursue a career, highlighting the benefits of their ongoing empowerment.

The purpose of this paper is to develop and test a model of idiosyncratic deals (i-deals), embedded in the processes of work-family enrichment.

Hierarchical linear regressions and indirect-effect analyses were used to analyze the data from 179 working parents surveyed in a Chinese city.

Successful i-deal negotiation was contingent on both personal initiative of the employee and a positive influx of support from the family to the work domain. Additionally, the results suggested that: development i-deals enriched the intra-work role experience by customizing intrinsic work features and thus enhancing intrinsic motivation. Flexibility i-deals enriched the work-to-family boundary experience through increased instrumentality of the work role, connected to the economic basis of employment.

Providing new insights into the antecedents and consequences of i-deals, the study suggested a model through which employees can create balance and use synergies in their work-life quality. Based on single-source cross-sectional data, the results are preliminary.

Human resource management needs to consider the family lives of employees, especially in the Chinese culture. The authors further discussed applications of and limitations to the use of i-deals.

The study provides a new approach to addressing the issue of balance between different social roles.

The study is the first to investigate i-deals in the context of work-family enrichment, explore the role experiences of i-deal recipients, and link i-deals to distinct motivational processes.
