Objective of the thesis is to develop a finite element that is effective for simulation of thin-walled behavior, such as in metal forming processes. The thesis includes six chapters and is structured as follows. The first chapter presents the objects for the research. The second chapter introduces background methods which will be incorporated in the solid-shell elements. The third chapter develops an alternative ANS technique and applies it to the solid-shell elements. As a result, in that chapter a new solid-shell element based on the alternative ANS technique is proposed. Elastic applications of the just developed solid-shell element are illustrated in Chapter 4. In Chapter 5, plasticity theory and numerical problems in plasticity deformation are presented. The thesis specially concentrates on treating a current industrial problem: spring back prediction. Results in Chapter 4 and Chapter 5 demonstrate the capabilities of the proposed solid-shell element. Chapter 6 withdraws conclusions and then makes some remarkable future developments.

This report presents an optimization of the allocation of maintenance resources for Air Navigation Service (ANS) equipment of which LFV is responsible for the maintenance. The purpose the authors have worked after is to research ways of minimizing travelling time linked to maintenance visits for ANS equipment, this report includes the suggestions where the maintenance facilities should be placed in order to minimize the total travelling time. The report describes the problem background and presents the customer, LFV. It includes a chapter on some of the theories used for facility location and routing, and also presents methods for reducing the total travelling time used for maintenance visits annually. The authors have worked with a given set of airports in Sweden. Information about the general work with maintenance as well as the annual demand of maintenance, including the frequency of visits, for each airport included in this project was received by Pär Oberger, the task expert and contact at LFV for this report. A model for facility location based on the p-median model have been created and used when solving the problem, it was written in AMPL and solved with the CPLEX solver. The model was modified with two additional constraints regulating the minimum annual working time and the maximum distance for one-way travelling. The authors deems that a solution with five facilities is better since the benefit of additional facilities, in term of lower total distance, do not compensate for the assumed cost of establishing them.
