Precision Measurements of Crashworthiness of Automotive Longitudinals in Aluminium and Steel
In this study, a comparison of dynamic mechanical behaviour of thin sheet boxes (crash energy absorbers) of two different materials (aluminium and steel), submitted to crash tests by means of a large Hopkinson bar, is reported. For the steel boxes, the experimental results show that the first peak load value is higher than the successive ones; for aluminium boxes the first peak load is almost at the same level of the successive ones. An analysis of such a difference is given by studying the wave phenomena occurring at the beginning of the crash test and the mechanical behaviour of materials.
