Damage evolution and element removal for ductile metals

The damage evolution capability for ductile metals:

  • assumes that damage is characterized by the progressive degradation of the material stiffness, leading to material failure;

  • must be used in combination with a damage initiation criterion for ductile metals (Damage initiation for ductile metals);

  • uses mesh-independent measures (either plastic displacement or physical energy dissipation) to drive the evolution of damage after damage initiation;

  • takes into account the combined effect of different damage mechanisms acting simultaneously on the same material and includes options to specify how each mechanism contributes to the overall material degradation; and

  • offers options for what occurs upon failure, including the removal of elements from the mesh.
