With debate in the industry turning lately to the power and consequence of lightning strikes on various items of electrical and electronic equipment ICORE International commissioned a series of tests, conducted by the Lightning Test and Technology Unit at Abingdon‐based Culham Laboratories, into the effects of lightning strikes on their conduit products.

The purpose of this paper is to develop a method to model entire structures on a large scale, at the same time taking into account localized non-linear phenomena of the discrete microstructure of cohesive-frictional materials.

Finite element (FEM) based continuum methods are generally considered appropriate as long as solutions are smooth. However, when discontinuities like cracks and fragmentation appear and evolve, application of models that take into account (evolving) microstructures may be advantageous. One popular model to simulate behavior of cohesive-frictional materials is the discrete element method (DEM). However, even if the microscale is close to the macroscale, DEMs are computationally expensive and can only be applied to relatively small specimen sizes and time intervals. Hence, a method is desirable that combines efficiency of FEM with accuracy of DEM by adaptively switching from the continuous to the discrete model where necessary.

An existing method which allows smooth transition between discrete and continuous models is the quasicontinuum method, developed in the field of atomistic simulations. It is taken as a starting point and its concepts are extended to applications in structural mechanics in this paper. The kinematics in the method presented herein is obtained from FEM whereas DEM yields the constitutive behavior. With respect to the constitutive law, three levels of resolution – continuous, intermediate and discrete – are introduced.

The overall concept combines model adaptation with adaptive mesh refinement with the aim to obtain a most efficient and accurate solution.

Current procedures of buckling load estimation for thin-walled structures may provide very conservative estimates. Their refinement offers the potential to use structure and material properties more efficiently. Due to the large variety of design variables, for example laminate layup in composite structures, a prohibitively large number of tests would be required for experimental assessment, and thus reliable numerical techniques are of particular interest. The purpose of this paper is to analyze different methods of numerical buckling load estimation, formulate simulation procedures suitable for commercial software and give recommendations regarding their application. All investigations have been carried out for cylindrical composite shells; however similar approaches are feasible for other structures as well.

The authors develop a concept to apply artificial load imperfections with the aim to estimate as good as possible lower bounds for the buckling loads of shells for which the actual physical imperfections are not known. Single and triple perturbation load approach, global and local dynamic perturbation approach and path following techniques are applied to the analysis of a cylindrical composite shell with known buckling characteristics. Results of simulations are compared with published experimental data.

A single perturbation load approach is reproduced and modified. Buckling behavior for negative values of the perturbation load is examined and a pattern similar to a positive perturbation load is observed. Simulations with three perturbation forces show a decreased (i. e. more critical) value of the buckling load compared to the single perturbation load approach. Global and local dynamic perturbation approaches exhibit a behavior suitable for lower bound estimation for structures with arbitrary geometries.

Various load imperfection approaches to buckling load estimation are validated and compared. All investigated methods do not require knowledge of the real geometrical imperfections of the structure. Simulations were performed using a commercial finite element code. Investigations of sensitivity with respect to a single perturbation load are extended to the negative range of the perturbation load amplitude. A specific pattern for a global perturbation approach was developed, and based on it a novel simulation procedure is proposed.

This chapter examines the role of national governments in the evolution of power relationships in multinational companies. The empirical study is based on a longitudinal analysis (2000–2011) of the EADS Group (European Aeronautic Defence and Space Company), which resulted from the merger of French company Aérospatiale-Matra, German company DASA and Spanish company CASA. The analysis focuses on the impact of national governments that were involved in the creation of EADS and national governments of emerging economies which have become priority markets for the company. The findings show that the political context has strongly influenced the balance of power within the EADS group.

Following on from the thawing‐out of the cold war and the revolutions of Eastern Europe, the threat of lower armament levels provided opportunities for the rationalisation of European defence and its military‐industrial complexes. Coupled with the continuing threat of reduced defence expenditures and increasing competition, defence companies have reacted to the changes with a number of strategic moves involving mergers and acquisitions, market nicheing and diversification, in addition to lay‐offs and plant closures. More recently, moves towards a single European defence industry have been discussed among the major contributing member countries and their industry leaders. The integration of a defence aerospace industry seems well placed to succeed, given French co‐operation, and this should produce a formidable, global competitor. East and Central Europe’s contribution to the equation is questionable, although the early signs are that west European defence companies are establishing firm footholds in the region against strong US competition.

Since corporate ventures operate under the organizational conditions of a parent company, this article aims to highlight key conditions influencing the success of a new venture.

Two cases of corporate venturing are analyzed regarding their performance since they are characterized by different conditions within one international consumer‐goods company. Hence, the literature on corporate entrepreneurship is reviewed and combined with a case study to explore the role and drivers of organizational conditions in the inception and development of new corporate ventures.

The case study reveals two key organizational differences pertaining to corporate new ventures — procedural clarity and procedural discipline. These differences mitigate the variety of risks that corporate entrepreneurs face and smooth or hinder their way to evolve their venture from ideas to business.

As the study includes two venturing cases within the same company in the fast moving consumer goods industry (FMCG), the findings are so far limited to the characteristics of this company type and its sector.

This article supports mid‐level managers to run corporate ventures more successfully by introducing a clear action plan with well defined phases. Individual managers' impact should be limited and linked to a more objective network‐structure.

In contrast to previous literature, this paper highlights the influence of organizational conditions under which corporate ventures are initiated and operated. Additionally, there are further factors identified, the ventures' internal visibility, and the knowledge support by the parent company, which will influence the venture's success or failure.

Until today a central register for medical guidelines has not been established in Austria. Hence, the study at hand aims to identify important success factors for medical guidelines in Austria in order to fully support the future activities of organisations developing these guidelines.

Using a specially‐developed questionnaire, 137 potential Austrian guideline developers were asked about the anticipated benefits of a common guideline register and a standardised method for guideline development by means of a complete inventory count for Austria.

Approximately 73 per cent of Austrian guideline developers know of existing online guideline registers. Nearly 77 per cent know neither of an instrument to evaluate the guidelines in a methodical way, nor of the Council of Europe's recommendation. Around 63 per cent expect an improvement in the quality of the guidelines by implementing a standardised method.

The present study provides the results of the first complete inventory count of guideline developers in Austria and can be used as an orientation for future activities.

The realisation of the success factors would increase the quality of national guidelines and would boost the implementation of best practices such as evidence‐based‐medicine into the Austrian health care system.

The study shows for the first time the necessity of support in order to improve the quality of Austrian guidelines from the point of view of potential developers.
