Abstract
Ductile damages often happen on metal structures under large deformations. In the current paper, the ductile damage criteria are discussed from the microscopic mechanism to metal ductile fracture models. Abaqus FEA makes the metal ductile damage criteria easy to be applied for practical problems. Therefore, the paper finally presents the detailed implementation of the ductile damage criteria in Abaqus FEA to describe the metal damage and degradation, simulating the ductile failure process with higher fidelity.
