Dynamic problems are solved using beam theory and shear lag approximations, and also FEM. For a laminated plate incorporating through-thickness fibers, highlights are: 1) Inertia complicates the fiber pullout problem considerably. 2) Disturbances propagate along frictionally coupled fibers at less than the bar wave speed. 3) Unstable regimes appear in interfacial friction. 4) Large scale bridging creates oscillatory, predominately mode II crack profiles and 5) strongly modifies fracture at low to intermediate velocities. These results imply that dynamic delamination damage evolution will be dominated by distributed (not localized) bridging and friction effects. Solutions for single cracks with small process zones are less relevant than those for multiple cracks with large scale bridging, for which some initial solutions are discussed.
