摘要: Shock fracture mechanisms of different scales were investigated on epoxy composite materials reinforced with silicon carbide microparticles concentrations. It is shown that the high heterogeneity composites at structural one factors responsible for their physical and mechanical properties. Under dynamic loading, material reveals a developed scale hierarchy which provides self-consistent deformation bulk lead rotational modes. As result, microcracks develop due to low shear strain limited in addition by reinforcing particles. At start main crack, microscale dominate, whereas propagation its front governed macroscale mechanisms.
