Abstract

We obtain a closed analytic solution of the problem of development of local fracture in a composition containing a rigid inclusion in the form of a fiber. Under the action of the load, near the ends of the inclusion, we observe the development of plastic zones (prefracture bands). These zones are modeled by the discontinuities of tangential displacements on the matrix-inclusion boundary. In the prefracture bands, the material is elastoplastic with hardening. Outside these bands, the material is elastic. The dimensions of the bands are determined. By analogy with the well-known δ-model in the theory of cracks, we use a deformation criterion to find the ultimate load of exfoliation of the fiber.
