*BEAM GENERAL SECTION
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.
