1. 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.
