Abstract

Damage of metals is a progressive physical process which finally leads to the failure of them. In this study, first, a coupled elastic- plastic- LEMAITRE'S DUCTILE DAMAGE MODEL combined with LARGE DEFORMATIONS THEORY is developed and implemented as a subroutine into ABAQUS/EXPLfCIT code. Then, by performing standard tensile and Vickers micro-hardness tests, mechanical and damage properties for St 14 steel are determined. For validation of the damage model and also identified properties, CUTTING AND FINE CUTTING PROCESSES are simulated by the model in two cases of large and small deformation theories. Comparison of the numerical simulation results and experimental reports show that LEMAITRE'S DUCTILE DAMAGE MODEL combined with large deformation theory can accurately predict damage evolution, crack initiation, propagation, and DUCTILE FRACTURE in the metal forming processes with large deformations.
