====== ELAMET ======
===== Description =====
Elastic constitutive law coupled with metallurgical effects for solid at variable temperature 
==== The model ====
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 [[laws:thmet|THMET]]

All the material parameters of this constitutive law are stored on a separate data file available to the pre-processor. The description of this file is with the law [[laws:METAMEC|METAMEC]].
===== Stresses =====
==== Number of stresses ====
6 for 3D state \\ 4 for the other cases
==== Meaning ====
The stresses are the components of CAUCHY stress tensor in global (X,Y,Z) coordinates. \\
For the 3-D state:
|SIG(1)|$\sigma_{xx}$|
|SIG(2)|$\sigma_{yy}$|
|SIG(3)|$\sigma_{zz}$|
|SIG(4)|$\sigma_{xy}$|
|SIG(5)|$\sigma_{xz}$|
|SIG(6)|$\sigma_{yz}$|
For the other cases:
|SIG(1)|$\sigma_{xx}$|
|SIG(2)|$\sigma_{yy}$|
|SIG(3)|$\sigma_{xy}$|
|SIG(4)|$\sigma_{zz}$|
===== State variables =====
==== Number of state variables ====
1
==== List of state variables ====
|Q(1)| = element thickness (t) in plane stress state\\ = 1 in plane strain state \\ = circumferential strain rate $\dot{\epsilon_\theta}$ in axisymmetric state \\ = 0 in 3-D state \\ = element thickness (t) in generalized plane state
