A new material technology for achieving both crashworthiness and weight reduction of a vehicle body using absorbing steel with higher strain-rate sensitivity is presented. In applying this technology, it is found that 590 N/mm2 grade dual-phase steel, having a microstructure of both ferritic and martensitic phases, and complex-phase steel which is characteristic to transformation-induced plasticity of retained austenite, are promising high-tensile steels with higher strain-rate sensitivity and outstanding energy-absorbing performance. The application of these materials to the front side member makes it possible to reduce the plate thickness by 15%. The three fundamental approaches with which this technology is based are presented.
