Couplage endommagement-décalcification du béton
Chemo-mechanical damage is among the leading problems involved in the development of predictive tools for the safety of nuclear waste storage facilities. Once the constitutive relations and the coupled governing equations have been derived, a key factor is to develop sound and robust computational techniques because in most situations, the calibration of the model parameters derives from inverse analysis techniques. In this contribution, we present a model for coupled mechanical damage and leaching of the cement paste in concrete. Through the analysis of mesh refinment, the accuracy and objectivity of the computational model is discussed. Finally, a sensitivity analysis of the major model parameters involved in the constitutive relations is presented.
