*MATTEMP

Data format:

A single line with four values

IMAT ALPHA TREF

Status :

Optional

Purpose :

To define a thermal expansion law associated with already existing material properties.

Details :

Parameter	Description
IMAT	Identification number of the material property (must have been previously defined through a *MAT keyword).
ALPHA	Thermal expansion coefficient
TREF	Reference temperature corresponding to null thermal elongation.

Note

The thermal elongation DL depends on the local temperature T through DL = ALPHA*(T-TREF)
