Could someone tell me the details about MAT_173 Mohr-coulomb model in LS-DYNA ?

  Is damage considered in this model or not? Associate flow rule or non-associate flow rule?
  I didn't find any illustrations in the user manual or theory manual.
  Thank you in advance.

  Damage is not considered, do check the pg-80 of the Manuel vol 11
  Cheers, Ram

  The direction of the plastic strain increment depends on the dilatation angle PSI. The material has a non-associative flow rule when PSI is different from PHI. See Remark 1 in the manual under MAT_173.
