This talk gives an introduction in the latest trends in occupant crash simulation. Main topics of this talk are model validation, examples of system analyses and hardware and software requirements of occupant crash simulation. It ...

This talk presents FEM modelling of adhesives and discusses its numerical aspects, pyshical behavior and possible material models in detail. KS2 specimen tests, T-component tests and full car crash tests are discussed in this talk, ...

In the frame of the development of a calculation method for adhesive joints experimental uniaxial und combined mechanical testing is based on the continuumsmechanic and the results with material equations and a failure criterion for ...

In this talk new features of the LS-DYNA version 971 R3 and R4 are presented as well as the latest improvements in LSTC dummy development. The talk concludes with an outlook of the version 980 of LS-DYNA and a conclusion.

This presentation concerns the generation of material data using neural networks. On the basis of polyamide it is examined, if a standardised procedure can be used for the characterization of material performance against different ...

The repeated performance of structural analysis, e.g., within a reliability based optimization, for realworld problems require a high computational effort. Due to the complexity of the real-world investigations, which are based on ...

This paper presents new features of the optimization post processing tool D-SPEX. The features are explained by means of various examples. The visualization of meta-models has been developed to a point where it can be a valuable tool ...

This paper presents comparisons between two types of structural optimization methods currently available in the commercial program Genesis. The paper describes the traditional and established topology method and discusses the ...

Most engineering optimization problems have more than one objective. Often these objectives conflict such that no single solution can be considered optimum with respect to all objectives. Then, the optimum to this problem is a set of ...

This paper summarizes the development status of LS-OPT® Version 3.3 and focuses mainly on the following new features: (i) Radial Basis Function Networks, (ii) Multi-objective Optimization (MOO), (iii) Metamodel-based MOO, (iv) ...
