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...

This study presents the crashworthiness performance of Al6061 tubes with stiffened quatrefoil sections under axial and oblique impact conditions. Influences different types stiffeners through depth in design a sectional crash absorber structure are investigated, numerically. Four stiffener patterns considered angles 0º, 10º, 20º, 30º measured from horizontal axis. Force-displacement characteris...

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...
