VISCOUS: Specify viscous material properties for the two-layer viscoplastic model.
This option is used to d efine the viscous properties for the two-layer viscoplastic ma terial model. It must b e
used in conjunction with the

ELASTIC and
*
PLASTIC options.

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 tem perature. 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 la w.
Set LAW=USER to input the creep law using user subroutine CREEP.
Data lines for LAW=TIME or LAW=STRAIN:
First line:
1. A. (Units of F L T .)
2. n.
3. m.
4. f.
5. Temperature.
6. First field variable.
