Brief Abstract: Multiscale methods are presented for modeling the dynamics of fiber reinforced composite structures using the linearized peridynamic formulation. Asymptotic analysis delivers a new multi-scale numerical method that captures the dynamics at structural length scales while at the same time is capable of resolving the dynamics at the length scales of the fiber reinforcement. The new numerical method is able to extract this information at a cost that is anticipated to be far less than the direct numerical simulation of structural components made from multiple plies containing thousands of fibers.
