Peculiarities of the Mechanical Response of Heterogeneous Materials with Highly Deformable Interfaces

Peculiarities of the deformation and fracture of heterogeneous materials with a large fraction of interfacial regions (interfacial materials) under the action of complex alternating loads have been studied by computer-aided simulation. The dependence of the character of fracture, deformability, dissipation of the applied energy, and strain distribution in the material bulk on the frequency of cyclic loading was determined. High-frequency vibrations at a frequency much greater than that of the natural oscillations may significantly increase the deformability of interfacial materials.
