    Sammanfattning : The protection of shipping does not come without hazards and threats for military forces, individual civilian ship operators and crews. With particular focus on security threats, this thesis is about how to prepare for such operations without introducing unnecessary risks, i.e., supporting conscious risk-taking related to ship security.

    Sammanfattning : The current trend in industry to encourage engineering designers to take an active part in the analysis of their own design solutions is apparent in many companies today, domestically as well as abroad.From a research project with the objective to develop a computer-based design system for the design of lightweight grippers, one of the major difficulties was to overcome the system users’ lack of knowledge and experience in the design of lightweight structures and Computer-Based Design Analysis (CBDA).

  3. 3. Fundamentals of a Methodology for Predictive Design Analysis

    Författare :Martin Eriksson; Produktutveckling; []

    Sammanfattning : The rapid development of computer-based design analysis tools and methods such as the finite element method (FEM) within computational structural mechanics (CSM), computational fluid dynamics (CFD), and multi-body systems (MBS) during recent decades has fundamentally changed the way in which products are designed and developed. Among the many advantages observed in industrial practice, one can mention improved understanding of product properties and behavior, the possibility to optimize critical design parameters and to optimize parts as well as the entire product at a system level, the possibility to explore a design space during the synthesis activity, and a decrease of the need for physical testing and thus of the number of physical prototypes needed.

    Sammanfattning : In this thesis we consider errors arising from finite difference operators on summation-by-parts (SBP) form, used in the discretisation of partial differential equations. The SBP operators are augmented with simultaneous-approximation-terms (SATs) to weakly impose boundary conditions. LÄS MER
