Modelling of uniaxial creep in ceramic matrix composites
A microstructurally-informed model is developed to describe the uniaxial creep behaviour of a bidirectionally reinforced composite consisting of alumina fibres embedded in a silicon carbide matrix. The model takes into account the creep of fibres and matrix, matrix cracking and the axial stress distributions within the composite. The latter are determined from a modified shear lag analysis which includes the Poisson effect and uses a critical interfacial shear stress as criterion for debonding. This micromechanical model allows the characterisation of the primary and secondary creep stages.
