Abstract

The problem of designing automotive bodies with improved crashworthiness but weighting less is one of the most challenging and critical engineering problems which the automobile industry must tackle. The automotive industry is tackling such critical design problems by following two main lines:
the development of future materials and the use of existing light materials, which are stable and absorb energy under impact loading (eg high strength steels, high strength aluminium alloys, magnesium alloy, composites, etc);
the effective implementation, starting from the early stages, in the design and production process of vehicle structures, of crash effect analysis given by numerical computational codes.

The two developments are strictly connected and give rise to some very specific and advanced research needs in different scientific disciplines. The present report identifies some of the most urgent research needs and proposes a method based on advanced precision testing under crash loading of automotive materials and body structures in order to:
evaluate and to increase the accuracy of material models at high strain rate;
evaluate and increase the accuracy of computational predictions of computer codes. odes.
