An analytical approach is presented to study the failure process for fiber composite materials (CM). Failure processes are modelled in a computer, including a stage for model construction and a loading and failure stage for the model CM as a simulation of CM behavior. Three composite materials were considered with an aluminum matrix reinforced with fibers of carbon, boron (coated with B/sub 4/C), and silicon carbide. The authors found that failure of a CM develops by one of three micromechanisms depending on the ratio of mechanical characteristics of interaction, i.e., retention in the CM of fiber strength and matrix ductility and creation of strong component bonds. The sequence of elementary acts forming one or another failure macromechanism is presented.
