In recent years, the usage of high-strength steel is increasing in order to improve the rate of body weight reduction and the safety performance of a vehicle from crash. The Bauschinger effect is generally strong in high-strength steel sheets. Material properties used in crash analysis is conventionally treated as isotropic hardening material. However, the analysis results such as average loading and buckling wavelength from analysis deviates with those from tests, which is observed in some axial collapse problems of hat section frame that is composed of high-strength steel sheet. When axial collapse occurs in the hat cross section frame, buckling occurs along with a frame ridge rolling.

A cable grommet is a tube ring through which an electric cable passes. They are usually made of rubber or metal. The cable grommet is used to protect, improve friction or seal cables passing through it, from a possible mechanical or chemical attack and for aesthetic look. It becomes very important to determine the optimum length of the grommet used for particular application. Bigger length will have results into folding of grommet and lesser length will yield into stretching of rubber grommet. Finite element simulation technique presented in this paper can be used to determine the optimum geometry of the grommet. Component used for this study is an automotive door harness rubber grommet.

Components made of short-fiber-reinforced plastics (SFRP) are stressed highly both mechanically and thermally. Therefore an intelligent component design is required in order to fully exploit the potential of these materials. Hence, the design of such components must be based on a reliable strength assessment. For this purpose models for the description of the anisotropic and elasto-plastic failure behavior of SFRP are required. In contrast to the widespread use of SFRP, methods for a reliable strength assessment based on FE analyses for components made of these materials have not been sufficiently developed yet. This paper presents an approach for the strength assessment of SFRP components based on FE analyses. In the scope of this appropriate failure limits and failure criteria for these materials are presented.

In research and development environment and concept design, people involved in new projects often need to design a completely new shape for the structure target of the analysis. The loading conditions and constraints are usually known but the designer hardly knows how to create the geometry of the structure that meets the requirements of the project and that can be manufactured at the same time respecting the target costs. In this paper is presented the topology optimization of a motorcycle swing arm, starting from a design space which takes into account the overall dimensions, and trying to minimize the mass while maximizing stiffness. The use of Tosca Structure, that drives the FEM simulation of the swing arm performed with Abaqus, allowed to obtain a shape that can be manufactured in compliance with the requirements of the project.

Research Associate Stefan Sicklinger employed SIMULIA’s co-simulation engine (CSE) to link four physics—flow, structure, multi-body dynamics and control—into highly accurate 3D models of wind turbine startup, run and emergency braking. Abaqus FEA’s robust solver provided extremely realistic simulations of the flexible turbine blades during operation.
