![عکس صفحه اول مقاله: Surface crack problem for functionally graded magnetoelectroelastic coating–homogeneous elastic substrate system under anti-plane mechanical and in-plane electric and magnetic loading Surface crack problem for functionally graded magnetoelectroelastic coating–homogeneous elastic substrate system under anti-plane mechanical and in-plane electric and magnetic loading](/preview/png/771455.png)
A functionally graded magnetoelectroelastic material layer bonded to a homogeneous elastic substrate is investigated. The functionally graded magnetoelectroelastic layer contains a surface crack that is perpendicular to the surface of the medium. The structure is subjected to anti-plane mechanical and in-plane electric and magnetic loads, the crack problem involves the anti-plane elastic field coupled with the in-plane electric and magnetic field. The elastic layer can be an ideal insulator or an ideal conductor. Integral transform and dislocation density functions are employed to reduce the problem to the solution of a system of singular integral equations. Numerical results show the influences of the material gradient parameter and crack configuration on field intensity factors and energy release rates of the functionally graded magnetoelectroelastic coating–homogeneous elastic substrate structure.
