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.
