Optional parameters (if neither ELASTIC nor LINEAR is included, elastic-plastic response is
assumed):

DEPENDENCIES

Set this parameter equal to the number of field variable dependencies included in the torque–twist
relationship, in addition to temperature.

If this parameter is omitted, it is assumed that the

torque–twist relationship is constant or depends 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.

ELASTIC

Include this parameter if the torque–twist relationship is nonlinear but elastic.

LINEAR

Include this parameter if the torque varies linearly with twist.

Data lines if the LINEAR parameter is included:

First line:

1. Torsional stiffness of the section.

2. Temperature.

3. First field variable.

4. Second field variable.

5. Etc., up to six field variables.
