The ply constitutive relations of an energy-based model for distributed microcracking in continuous fiber reinforced metal matrix composites are presented. Simple models for damage progression are used in conjunction with these damage dependent constitutive relations to allow the prediction of fatigue life under constant amplitude, isothermal conditions. The microcracking model is discussed in the context of fatigue analysis of unnotched titanium matrix composite laminates. Analytical results generated by using this model in a unidirectional laminate analysis algorithm are presented and compared with experimental results. [S0094-4289(00)03104-2]
