A multiscale experimentally-based finite element model to predict microstructure and damage evolution in martensitic steels

The objective of this work is to investigate the plastic deformation and associated microstructural evolution and damage in a martensitic steel at multiple length scales, using a combination of finite-element (FE) modelling and experimental measurements. A multiscale model is developed to predict da...
