Abstract

High strength TRIP (Transformation Induced Plasticity)-aided steels combine high strength levels with excellent ductility, making them ideally suited for application in crash-relevant parts in the automotive industry. In order to assess the dynamic properties of TRIP-aided steels, an extended experimental program was set up to test different compositions (CMnAl, CMnSi...) with strain rates varying from 500 to 2000 s -1. Observation of the energy absorption, tensile strength, ultimate and uniform deformation as a function of strain rate learns that TRIP steels also have excellent properties in dynamic conditions. Several phenomenological material models were investigated to describe the high strain rate behaviour of these complex steel grades. It was found that an extended version of the Ludwig model and the Johnson-Cook model give good results.
