Elastic constitutive law coupled with metallurgical effects for solid at variable temperature
Non-linear analysis of elastic solids coupled with thermal and metallurgical analysis.
The phase transformations induce modifications of the elastic moduli, volume changes. The temperature changes induce thermal expansion.
This constitutive law must be used together with law THMET
