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.
