Durability of CFRP laminates under thermomechanical loading: A micro–meso damage model

A pragmatic approach is here proposed for the description of the degradation of laminated composites under cyclic loading, including the effect of oxidation. It is based on an hybrid micro- and mesomodeling of the degradation which includes and generalizes classical micromechanical approaches for static loading. The effects of cyclic loading and of the environment are then taken into account through the consecutive decrease in critical quantities.
