|Summary||The non-linear stress-strain curve obtains under tensile loading, is related to a multi-scale development of damage phenomena like matrix microcracking, fibre or bundle debonding and fibre breakage. To describe this damage evolution and its consequences on the industrial components mechanical behaviour, correlation between the different scales and reliable homogenization procedure have been studied. This micro-macro model is applied to various SiC-SiC (CVI) and a C-SiC (CVI) made by S.E.P (Société Européenne de Propulsion, France).
