*VISCOUS
21.5 *VISCOUS: Specify viscous material propertiesfor the two-layer viscoplastic model.
This option is used to define the viscous properties for the two-layer viscoplastic mat erial model. It must be
used in conjunction with the *ELASTIC and *PLASTIC options.
Product: ABAQUS/Standard

Optional parameters:
DEPENDENCIES
Set this parameter equal to the number of field variable dependencies included in the definition of
the material properties, in addition to temperature. If this parameter is omitted, it is assumed that
the material properties depend only on temperature. See “Specifying field variable dependence”
in “Material data definition,” Section 16.1.2 of the ABAQUS Analysis User’s Manual, for more
information.
LAW
Set LAW=STRAIN(default) to choose a strain-hardening power law.
Set LAW=TIME to choose a time-hardening power law.
Set LAW=USER to input the creep law using user subroutine CREEP.
