Abstract : A first version of a multiscale, multiphysic & hybrid model –called virtual material– for predictions on SelfHealing Ceramic Matrix Composite's (CMCs) lifetime is presented. The model has a mechanical and a chemical part, which are presented here in their actual state of development. The mechanical part provides precise data for the chemical models through an hybrid –melting continuum damage macro model & discrete crack surfaces– representation of the morphology of the crack network at yarn scale. The chemical part should provide predictions on the structure's lifetime using a model of the selfhealing process, not yet achieved then not presented here, and a model of fiber subcritical failure under mechanical and chemical load.
