Pre-fracture zone model on magnetoelectrically permeable interface crack between two dissimilar magnetoelectroelastic materials

Abstract

A plane strain problem for two magnetoelectroelastic (MEE) half-planes adhered by a thin isotropic interlayer is considered. A novel crack model, i.e., a magnetoelectrically permeable interface crack with pre-fracture zones is introduced for MEE bimaterial system. The stresses in pre-fracture zones and the lengths of pre-fracture zones are unknown, which are determined by solving the corresponding Hilbert problem and solving nonlinear equations introduced by yielding condition on the pre-fracture zones. Some particular cases are further analyzed and numerically discussed. In the suggested model, any singularities connected with the crack are eliminated, and the results presented in this paper should have potential applications to the design of multilayered MEE structures and devices.
