Integral Equations of Plane Magnetoelectroelasticity for a Cracked Bimaterial With Thin Inclusions

Resumo

Based on the combined application of the Stroh formalism and the theory of functions of complex variable, we deduce dual integral equations for a magnetoelectroelastic bimaterial. For the first time, we construct the integral representations of the Stroh complex potentials and the explicit expressions for all kernels in terms of the parameters and matrices of the applied formalism. This noticeably reduces the amount of computations required to get the governing equations of the boundary-element methods. The explicit formulas are obtained for the principal parts of the complex potentials. These formulas enable us to consider homogeneous magnetoelectromechanical loads applied at infinity. The obtained equations, together with previously developed models of thin deformable inclusions, are introduced in the computational algorithm of the boundary-element method with jump functions. The solution of test problems reveals high accuracy and efficiency of the proposed approach. Some solutions are presented for new problems posed for a magnetoelectroelastic bimaterial with thin inclusion.
