Abstract
The present work investigates the problem of cyclically symmetric cracks on the arc-shaped interface of a functionally graded magneto-electro-elastic layer bonded onto an orthotropic elastic substrate under anti-plane shear load. Based on the method of variable separation, this mixed boundary value problem is reduced to a Cauchy singular integral equation, which is solved numerically by the Lobatto–Chebyshev quadrature technique. Specialcasesof the model are used to verify the correctness of theoretical derivation and numerical computation in this work. Numerical results are presented to show the effects of geometrical and physical quantities on the stress intensity factors.
