An established multiscale model for materials is used as the basis for a failure model for fiber composites. The model’s computation is explained so that its results can be used to formulate the inputs to the failure model. The failure model proposed employs homogenization and disaggregation methods that are enabled by micro-scale modeling of the material’s constituents. This failure model is then used to define strength reductions in the composite at the micro-level. The strength reductions enable the definition of a progressive failure methodology for application to the micro-scale, and ultimately, the macro-scale composite. The failure model, the degradation model, and the multi-scale model they are based upon are combined in a computational program for inclusion in finite element software for efficient solving and prediction of intact and failed composite structural response. The model is then tested against existing experimental data as well as by experiments conducted by the author.
