  A first version of a multi-scale, multi-physic hybrid model --called virtual
material-- for predictions on Self-Healing 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 self-healing
process, not yet achieved then not presented here, and a model of fiber
sub-critical failure under mechanical and chemical load.
