Principle of the test
=================


1. Any thermal calculation is carried out, resulting in a temperature field.


2. This temperature field is used as a "source" of deformation:


*thermal: eps = + ALPHA* (TEMP - VALE_REF)


*hydration: eps = - B_ ENDOGE* HYDR


*drying: eps = + K_ DESSIC* (SECH - VALE_REF)

**Notes:**


* *It is the same temperature field (* TEMP *) that plays the role of* TEMP *,* HYDR *and* SECH *.*


* *The coefficients* ALPHA *,* B_ ENDOGE *,* B_ *,* K_ *,*, *K_ DESSIC* *,*, *,*, *K_*, *,*, *,* K_ *,*, *,* TEMP_REF *, and* VALE_REF *(temperature and drying) are chosen to obtain the same deformation.*


1. 3 mechanical problems are solved with the 3 previous loads. The same displacement field must be obtained for all 3 calculations.
