THMET
Description
Constitutive law of thermal conduction coupled with the effects of the metallurgical phase transformations
The model
This law is only used for non linear thermal analysis coupled with metallurgical analysis of isotropic solids.
This law takes account of the heat generated by metallurgical phase changes.
