Abstract

A study of the behaviour of shear deformable plate finite elements is carried out to determine why and under what conditions these elements lock, or become overly stiff. A new analytical technique is developed to derive the exact form of the shear constraints which are imposed on an element when its side‐to‐thickness ratio is large. The constraints are expressed in terms of the nodal degrees of freedom, and are interpreted as being either the proper Kirchhoff constraints or spurious locking constraints. To gain a better understanding of locking phenomena, the constraints which arise under full and reduced integration are derived for various plate elements. These include bilinear, biquadratic, eight‐node serendipity and heterosis elements. These analytical findings are compared with numerical results of isotropic and laminated composite plates, verifying the role that shear constraints play in determining the behaviour of thin shear deformable elements. The results of the present study lead to definitive conclusions regarding the origin of locking phenomena and the effect of reduced integration.

Abstract

An algorithm to calculate shape function values at specific points is presented. It applies to three‐dimensional serendipity elements with variable node numbers per side and, as a particular case, to plane and truss elements. The procedure is shown for the two‐dimensional case using the natural orthogonal reference system of the element and is then generalized to the three‐dimensional case. The source code of the described algorithms written in Fortran 77 is included.

Abstract

Purpose

The purpose of this paper is to investigate the changing research practices of historians, and to contrast their experiences of serendipity in physical and digital information environments.

Design/methodology/approach

In total, 20 historians in Southwestern Ontario participated in semi-structured, in-depth interviews. The interviews were transcribed and analyzed employing grounded theory. The analytical approach included memoing, the constant comparative method, and three phases of coding.

Findings

Four main themes were identified: agency, the importance of the physical library experience, digital information environments, and novel heuristic forms of serendipity. The authors found that scholars frequently used active verbs to describe their experience with serendipity. This suggests that agency is more involved in the experience than previous conceptualizations of serendipity have suggested, and led us to coin the term “incidental serendipity.” Other key findings include the need for digital tools to incorporate the context surrounding primary sources, and also to provide an organizational context much like what is encountered by patrons in library stacks.

Originality/value

The increased emphasis on digital materials should not come at the expense of the physical information environment, where historians often encounter serendipitous finds. A fine balance and a greater integration between digital and physical resources is needed in order to support scholars’ continued ability to make connections between materials. By showing the active role that historians take in their serendipitous encounters, this paper suggests that historical training is critical for eliciting incidental serendipitous encounters. The authors propose a novel approach, one that examines verbs in serendipity accounts.

Abstract

The use of algebraic languages such as REDUCE makes possible the automatic generation, from fairly concise data, of the main families of two and three dimensional C0 continuous finite element shape functions, with a high confidence in their correctness. This paper gives a tutorial introduction to the REDUCE language and describes how it was used to generate shape function routines.

Abstract

Gives a bibliographical review of the finite element methods (FEMs) applied for the linear and nonlinear, static and dynamic analyses of basic structural elements from the theoretical as well as practical points of view. The range of applications of FEMs in this area is wide and cannot be presented in a single paper; therefore aims to give the reader an encyclopaedic view on the subject. The bibliography at the end of the paper contains 2,025 references to papers, conference proceedings and theses/dissertations dealing with the analysis of beams, columns, rods, bars, cables, discs, blades, shafts, membranes, plates and shells that were published in 1992‐1995.

Abstract

Purpose

In “Coming across information serendipitously – Part 1: a process model” the authors identified common elements of researchers' experiences of “coming across information serendipitously”. These experiences involve a mix of unexpectedness and insight and lead to a valuable, unanticipated outcome. In this article, the authors aim to show how the elements of unexpectedness, insight and value form a framework for subjectively classifying whether a particular experience might be considered serendipitous and, if so, just how serendipitous.

Design/methodology/approach

The classification framework was constructed by analysing 46 experiences of coming across information serendipitously provided by 28 interdisciplinary researchers during critical incident interviews. “Serendipity stories” were written to summarise each experience and to facilitate their comparison. The common elements of unexpectedness, insight and value were identified in almost all the experiences.

Findings

The presence of different mixes of unexpectedness, insight and value in the interviewees' experiences define a multi‐dimensional conceptual space (which the authors call the “serendipity space”). In this space, different “strengths” of serendipity exist. The classification framework can be used to reason about whether an experience falls within the serendipity space and, if so, how “pure” or “dilute” it is.

Originality/value

The framework provides researchers from various disciplines with a structured means of reasoning about and classifying potentially serendipitous experiences.

Abstract

Purpose

This paper aims to investigate the distinctive role of serendipity in opportunity exploration. The study specifically explores how serendipity happens and the pattern of its occurrence. The paper attempts to break new ground in the study of serendipity within the entrepreneurship area. Serendipity is quite established in scientific literature and investigating this concept in the context of entrepreneurship contributes towards the discourse on why some firms are able to discover and realise opportunities that seem to present themselves sometimes out of nowhere.

Design/methodology/approach

The study uses multiple case studies, cross-country approaches and the causal mapping method.

Findings

The findings suggest that serendipity is likely to take place at the early stages of firm formation. In addition to the three patterns of serendipity that are well-known in accidental scientific discoveries, the authors identify and introduce “entrepreneurial serendipity” as a distinctive pattern in entrepreneurship, whereby entrepreneurs look for any opportunity to start a business and explore an appropriate opportunity that comes along.

Research limitations/implications

This research has several limitations that offer new opportunities for future research. Further research can be undertaken to compare successful fast-growth firms with unsuccessful firms to determine how entrepreneurs were exposed to serendipity and to what extent they were able to exploit and realise opportunities. A comparative study would also enhance the authors’ interpretation of the role of serendipity in these two types of firms and demonstrate the different levels of serendipity they are potentially exposed to. The debate on serendipity could benefit from quantitative research and some tangible measures of serendipity can be developed.

Practical implications

The findings help entrepreneurs understand elements involved in opportunity exploration. The role of serendipity and its sources offer some suggestions on how entrepreneurs can potentially expose themselves to serendipity. The role of networks is crucial to doing business, and entrepreneurs should be aware of expanding their personal and business networks. Being engaged in friendly, professional and academic networks helps in finding new opportunities. Perseverance, being alert to changes in the environment and commitment to clients in terms of high-quality products and services are other elements that may open new windows of opportunity.

Originality/value

This paper provides empirical evidence that serendipity does play an important role in nearly every investigated business, regardless of their size and age. Serendipity potentially leads to new opportunities and entrepreneurs can explore them to achieve growth. By investigating grown firms in New Zealand and Iran, the authors identified a new pattern of serendipity in terms of opportunity discovery. This unique pattern, entrepreneurial serendipity, is characterised by finding an unspecified opportunity through an orderly or haphazard search, which could happen with either high or low levels of knowledge.

Abstract

Purpose

The current understanding of serendipity is based primarily on studies employing westerners as the participants, and it remains uncertain whether or not this understanding would be pervasive under different cultures, such as in China. In addition, there is not a sufficient systematic investigation of context during the occurrence of serendipity in current studies. The purpose of this paper is to examine the above issues by conducting a follow-up empirical study with a group of Chinese scholars.

Design/methodology/approach

The social media application “WeChat” was employed as a research tool. A diary-based study was conducted and 16 participants were required to send to the researchers any cases of serendipity they encountered during a period of two weeks, and this was followed by a post-interview.

Findings

Chinese scholars experienced serendipity in line with the three main processes of: encountering unexpectedness, connection-making and recognising the value. An updated context-based serendipity model was constructed, where the role of context during each episode of experiencing serendipity was identified, including the external context (e.g. time, location and status), the social context and the internal context (e.g. precipitating conditions, sagacity/perceptiveness and emotion).

Originality/value

The updated context model provides a further understanding of the role played by context during the different processes of serendipity. The framework for experiencing serendipity has been expanded, and this may be used to classify the categories of serendipity.
