Validation de logiciels couplés THM en milieux poreux partiellement saturés: apport des solutions semi-explicites
Validation of numerical computer codes applied to thermal-hydraulical-mechanical coupling problems (THM) in partially saturated media should include the two following steps:
— firstly to validate implementation of THM coupled rheological model by comparing numerical (such as FE) solutions and both explicit and semi-explicit solutions in the linear case;
— secondly to validate some non linear algorithms by comparing numerical computer codes on the basis of classical problems or under benchmark exercises.
This paper is devoted to the first step. Principles and prospects of developpement of explicit and semi-explicit solutions and their use for validation are firstly presented. Two applications are then presented: a thick sphere submitted to thermal and hydraulical loadings (TH couplings) and the dessiccation-shrinkage of a wall and a pile constituted by a concrete (HM coupling).
