Comments

  1. Failure models are not available with global integration (N=0 in /PROP/SHELL) for shells.
  2. Keyword USER1, USER2 and USER3 refer to /FAIL/USERi for shell and brick elements.
  3. Up to 6 failure models can be applied to a single material, each failure model representing a failure mode.
  4. Failure models can be used for SPH simulation for all materials compatible with SPH formulation.
  5. Four failure models (FLD, JOHNSON, TAB1, and TBUTCHER) are compatible when X-FEM provided property TYPE1 (SHELL), TYPE11 (SH_SANDW), or TYPE51 is used.
  6. /FAIL/TAB1 and /PROP/TYPE51 cannot be used with XFEM yet.
  7. FAIL/ORTHSTRAIN is compatible with material or failure which could be used with orthotropic properties.
