Constitutive modelling of CMCs for non-proportional, multi-axial loadings
Abstract
Due to their exceptional specific mechanical properties at high temperature, CMC are promising materials for the aerospace industry. The combination of brittle matrices with brittle fibres leads to rather complex mechanical behaviours. Indeed, different crack networks can develop depending on the microstructure of the material and on the loading conditions, bringing some ductility to the structure. In that context, sizing a part made of CMC up to failure is a great challenge that necessarily relies on physically sound models and the associated identification and validation of experimental tests.
