Dynamic response of an interface crack between magnetoelectroelastic and functionally graded elastic layers

摘要：

　　The dynamic response of an interface crack between magnetoelectroelastic and functionally graded elastic layers under anti-plane shear and in-plane electric and magnetic impacts is investigated by the integral transform method.The mixed boundary value problem of the interface crack is reduced to dual integral equations,which can be further expressed in terms of a Fredholm integral equation of the second kind.The singular stress fields near the crack tip are obtained asymptotically,and the stress intensity factor (SIF) is defined.Based on the criterion of maximum hoop stress,the crack will propagate along the original crack plane and wont kink.Numerical results show that the dynamic SIF is influenced by the material properties and geometric size ratios.
