Implementation of a material model for TRIP-steels in LS-DYNA and comparison with test results

Daniel Hilding and Erik Schedin This paper describes the implementation of a new material model into LS-DYNA version 960, LSTC (1-4), a material model capable of predicting the TRIP-effect of HyTensX for different forming operations in different temperature scenarios. The implementation is verified by comparing measurements from three tension tests with simulations of the tension tests. The comparison shows good to excellent agreement, which is a strong indication that the implementation is correct and that the material model can be used to predict the hardening behavior of the material with good accuracy.
