| Abstract Scope |
In the present study, the effect of subsurface grain orientation on the strain localization in the ultra-thin (≤0.1 mm) ferritic steel sheet is investigated by means of in-situ electron backscatter diffraction (EBSD) technique and crystal plasticity finite element method (CPFEM). Microstructure evolution during uniaxial tensile deformation is monitored by the in-situ EBSD technique. The CPFE simulation is performed using the representative volume element (RVE) obtained by directly mapping EBSD data of the initial microstructure onto the FE mesh. The simulation can capture the inhomogeneous stress/strain distribution and the local hot spots of the ductile fracture initiation in terms of damage criterion and stress triaxiality. Furthermore, the plastic strain localization behavior is discussed based on the kinematic stability of crystallographic orientation to account for the failure in the ultra-thin ferritic steel sheet. |
