Damage initiation for ductile metals

The material damage initiation capability for ductile metals:

  • is intended as a general capability for predicting initiation of damage in metals, including sheet, extrusion, and cast metals as well as other materials;

  • can be used in combination with the damage evolution models for ductile metals described in Damage evolution and element removal for ductile metals;

  • allows the specification of more than one damage initiation criterion;

  • includes ductile, shear, forming limit diagram (FLD), forming limit stress diagram (FLSD) and Müschenborn-Sonne forming limit diagram (MSFLD) criteria for damage initiation;

  • includes in Abaqus/Explicit the Marciniak-Kuczynski (M-K) and Johnson-Cook criteria for damage initiation;

  • can be used in Abaqus/Standard in conjunction with Mises, Johnson-Cook, Hill, and Drucker-Prager plasticity (ductile, shear, FLD, FLSD, and MSFLD criteria); and

  • can be used in Abaqus/Explicit in conjunction with Mises and Johnson-Cook plasticity (ductile, shear, FLD, FLSD, MSFLD, Johnson-Cook, and MK criteria) and in conjunction with Hill and Drucker-Prager plasticity (ductile, shear, FLD, FLSD, MSFLD, and Johnson-Cook criteria).
