THERMAL EXPANSION: Define the thermal expansion behavior of beams.
This option can be used only in conjunction with the

BEAM G ENERAL SECTION
Optional parameter:
DEPENDENCIES
Set this parameter equal to the number of field variable dependencies for the thermal-expansion
coefficient, in addition to temperature. If this parameter is omitted, it is assum ed that the thermal-
expansion coefficient 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.
Data lines to define the t hermal expansion behavior:
First line:
1. Coefficient of thermal expansion.
2. Temperature.
3. First field variable.
4. Second field variable.
5. Etc., up to six field variables.
Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than six):
1. Seventh field variable.
2. Etc., up to eight field variables per line.
Repeat this set of data lines as o ften as necessary to define the thermal expansion coefficient as a
function of temperature and other p redefined field var iables.
