For the design of engineering structures and the assessment of their reliability it is of main interest to appraise the importance of input quantities in view of result quantities. Sensitivity analysis provides a versatile tool to ...

Potential scatter of simulation results caused, for example, by buckling, is still a challenging issue for predictability. Principle component analysis (PCA) and correlation clustering are well-known mathematical methods for data ...

In this paper, novel methods for the PRO-CHAIN strategy are presented, and their application is discussed for an example. PRO-CHAIN enables statistical analysis and multi-objective robust design- parameter optimization of forming ...

The local mechanical properties e.g. flow stress and fracture strain in an automotive component manufactured by deep drawing are inhomogeneous due to different local deformation degrees which affect the component behavior under crash ...

Generally, the manufacturing of complex structures involves various processes that yield the final product. Simulation methods are often used to optimize each single process step. When the manufacturing levels involve different ...

Linear static response structural optimization using the finite element method for linear static analysis has been significantly developed. However, there is very little development of structural optimization where a non linear static ...

This talk presents load cases, the SFE CONCEPT, design variables as well as geometrical constraints and MDO under the topic of evaluation of a seat crossmember study by using multidisciplinary optimization.

The presented paper is related to a global sensitivity analysis in the field of numerical simulations. The objects of investigation are different car side crash scenarios and the influence of model variable variation on the occupant ...

This paper reviews the features of LS-OPT® in the areas of design optimization, multi-disciplinary optimization, reliability-based optimization and multi-objective optimization. Relatively new features for solver job distribution are ...

This paper gives a preview of of LS-OPT/Topology version 2, a topology optimization tool. The focus is on its capabilities, current development directions, and integration into an industrial design environment. Examples of using the ...
