Notes:

  • The parameters of the template*to be filled in under the keyword factor* LKR from the DEFI_MATERIAU command.

  • The parameter COUPLAGE_P_VP allows you to activate (1) or not (0) the coupling between the plastic and viscoplastic mechanisms.

  • Parameters that have a value by default are optional.

  • The elastic parameters must be entered under the keyword ELAS_ORTH or ELAS_ISTR. The (visco) plastic anisotropy is of the transverse isotropic type.
