A procedure is described that predicts the mechanical behavior of a fibrous material by generating and analyzing finite element models of its three-dimensional microstructure. The approach is applicable to a class of materials with microstructures consisting of fibers connected at well-defined points. The procedure allows one to predict the effect of important sources of heterogeneity in these materials. Analyses determine initial elastic properties, failure mode, and strength of the composite; the failure analysis consists of tracking a progression of microfailures. The procedure is validated by comparison of predictions to test results.
