This paper gives an overview of recent developments in the prediction of damage evolution in continuous fiber metal matrix composites with silicon carbide fibers and titanium matrix material. In order to provide motivation for the modelling efforts described herein, recent experimental observations are first described in some detail. Next, a few attempts to model processing are mentioned. This is followed by a section detailing numerous research efforts currently underway to model various aspects of the process of damage development. These include: 1) interface debonding; 2) matrix inelasticity, including dislocation type viscoplasticity and microvoid growth; 3) radial cracking; and 4) oxidation induced damage. Several results recently obtained by the authors are described in further detail.
