Strain Rate Testing of Metallic Materials and their Modelling for use in CAE Based Automotive Crash Simulation Tools (Recommendations & Procedures)

The aim of this book is to provide guidelines to generate tensile strain rate test data for ferrous and non-ferrous sheet metals for use in finite element based automotive crash simulation tools. Specifically, measurement of the strength hardening in a sheet material resulting from strain rate testing using a high speed servo hydraulic test machine. Additionally, to provide guidelines to process raw test data, fit material model and format this data for application in crash simulation tools. It is not within the scope of these recommendations to advocate a material model to fit to strain rate test results, although useful models are referenced. Rather to give guidance on the error allowance in fitting model to test results. These guidelines are expected to have broader application in the transport industry sector.
