Optional parameter:
DEPENDENCIES
Set this param eter equal to the number of field variable dependencies for the therm al-expansion
coefficient, in addition to temperature. If this param eter is om itted, 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 A BAQU S Analysis User’s Manual,
for more information.
Data lines to define the thermal 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 D EPENDENCIES 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 variables.
