Fiber composites are attractive for various engineering applications owing to their excellent mechanical properties. One of these is their superior energy dissipation capability compared to other light-weight materials. An example where this can be beneficial is in structures that are meant for protection of army personnel and infrastructure from impact/blast loads. Since actual physical testing is prohibitively costly, or even impossible at times, successful designs of such structures often heavily rely on insightful modeling. In the first part of this talk, the various challenges involved in developing such models will be presented. Primarily, the focus will be on the difficulties in predicting correctly the formation, propagation and branching of cracks that form under dynamic loads in composites. In the second part of this talk, a recently developed computational multiscale model will be described, which provides an ideal framework to enable these predictions. This model is a promising tool for designing composite structures for protection of personnel and infrastructure against impact/blast loads.
