  • Crash worthiness studies of thin sheet metal structures by means of a large Hopkinson bar : Benefits for calibration of impact rigs and validation of numerical crash simulation


The Hopkinson's bar method allows the accurate measurement of load-displacement characteristics and the energy absorption capability of thin sheet metal structures. The advantage of this method is that it gives control of the stress wave propagation caused by impact loading. This information can be applied to the design of car safety structures of greater efficiency and is also to be used to improve the mathematical models in the F.E. codes.
