MBW-Damage

User subroutines of the Modified Bai–Wierzbicki (MBW) damage mechanics model

This MBW damage mechanics model is developed to describe the stress state dependent cleavage/ductile fracture properties of metallic materials.

MBW_v08.f is the current version of the user subroutine used by the group members. material_MBW_v08.inp is the corresponding input template of the material section.

For a more detailed description of the model formulation and calibration procedures, please refer to the following publications.
