FEM simulation to assess formability and crash performance is used increasingly in automobile industry in order to reduce development time of complete new vehicle models and platforms. The simulations give the finite deformation ...

It is well known that ductile failure of metal is occurring after a certain amount of plastic deformation. Therefore, knowledge about the deformation behavior of materials is required to understand damage processes and to describe the ...

Glass-fiber-reinforced polypropylene (GF PP) materials are increasingly being used by customers to replace metal and engineering polymers in structural automotive applications. Like all glass-fiber-reinforced thermoplastics, GF PP ...

Diese Präsentation führt in die Thematik von der Charakterisierung und Modellierung von kurzfaserverstärkten Kunststoffen ein. Der zweite Teil dieser Präsentation beinhaltet die Ermittlung von Faserorientierungen, Charakterisierung ...

Diese Präsentation führt in die Thematik von der Charakterisierung und Modellierung von kurzfaserverstärkten Kunststoffen ein. Der erste Teil beinhaltet die Prüfung von Kunststoffen, Dehnungs- und Spannungsberechnung als auch ...

The occurring failure modes and their dedicated tolerated number of load cycles of composite parts are influenced by many parameters. Parameters like fiber-orientation und fiber-content, environmental conditions such as temperature ...

The properties of thermoplastic polymers considerably depend on the process of moulding, irrespective of the geometry of the part and the used raw polymer. Both, the structure of the polymer resulting from moulding and the weld lines ...

LS-Dyna is a common code in explicit analysis. Starting in 1997 the implicit capabilities are continuously being enhanced. Up from v970 most of the subroutines and data arrays can be used by both explicit and implicit. Switching ...

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 ...

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 ...
