A CP approach based on a three-component dislocation density model to predict non-proportional anisotropic hardening behavior of ultra-thin sheet metals: (a) dimension of large specimen for the prior tension, ASTM E8 sub-size specimens for the second tension, and simulated equivalent plastic strain map after 25 mm tension; (b) CP predicted stress-strain curves of 0.1 mm thick ferritic stainless steel sheet during compression-tension along the rolling direction and comparison with Chaboche kinematic hardening model prediction; (c) dimension of V-bending test for 0.1 mm thick ferritic stainless steel sheet and FE model for V-bending test, and (d) comparison of springback profiles after V-bending of pre-deformed sample.
