Products: ABAQUS/Explicit ABAQUS/CAE
Benefits: The Johnson-Cook criterion for damage initiation in ductile metals is now available within the general framework of progressive damage and failure in ABAQUS/Explicit.
Description: The Johnson-Cook criterion is a special ductile damage initiation criterion in which the equivalent plastic strain at the onset of damage is given as an analytical function of the stress triaxiality. In previous versions ABAQUS/Explicit supported this criterion as a model for dynamic failure (“Dynamic failure models,” Section 18.2.8 of the ABAQUS Analysis User's Manual), and the criterion was available only with the Johnson-Cook plasticity model. The Johnson-Cook criterion is now supported within the framework of progressive damage and failure in ABAQUS/Explicit. It can now be used in combination with all metal plasticity models (including Johnson-Cook plasticity) as well as with the Drucker-Prager plasticity model.
