in order to reduce both the weight of vehicles and the damage of occupants in a crash event simultaneously, it is necessary to perform a multi-objective optimization of the automotive energy absorbing components. in this paper, axial impact crushing behavior of the aluminum foam-filled thin-walled tubes are studied by the finite element method using commercial software abaqus. comparison of the...

A finite element (FE) model of a 1998 Audi Model A8 has been developed for the crash analysis associated with the NHTSA NCAP program. The AUDI model A8 is an all aluminum four-door passenger vehicle; it is classified as a ‘large sedan’ car. The model developed is to be used to analyze frontal impact against a rigid barrier as specified in standard procedures associated with the assessment of pa...

In the realm of van design, researchers have been diligently working to enhance rollover crashworthiness while concurrently achieving lightweight body structures. Unlike front and side impacts, is impacted by a greater number structural dimensions material parameters. As such, this paper implements an unreplicated saturated factorial design conduct factor screening for vehicle crashworthiness. ...

A hardness-based model for tailor hardened boron steel is presented that takes into account the softened heat-affected zone of resistance spot welds. The computational model is designed for crashworthiness simulation of fully and partially hardened components obtained by tailored tooling. Five different hardness grades of 22MnB5 are used for model calibration. The proposed model is validated wi...
