Purpose The purpose of this paper is to provide a theoretical analysis of the fracture behavior of multiple axisymmetric interface cracks between a homogeneous isotropic layer and its functionally graded material (FGM) coating under torsional loading. Design/methodology/approach In this paper, the authors employ the distributed dislocation technique to the stress analysis, an FGM coating-substrate system under torsional loading with multiple axisymmetric cracks consist of annular and penny-shaped cracks. First, with the aid of the Hankel transform, the stress ﬁelds in the homogeneous layer and its FGM coating are obtained. The problem is then reduced to a set of singular integral equations with a Cauchy-type singularity. Unknown dislocation density is achieved by numerical solution of these integral equations which are employed to calculate the SIFs. Findings From the numerical results, the following key points were observed: first, for two types of the axisymmetric interface cracks, the SIFs decrease with growing in the values of the non-homogeneity. Second, the SIFs increase with increases in interface crack length. Third, the magnitude of the SIFs decreases with increases in the FGM coating thickness. Fourth, the interaction between cracks is an important factor affecting the SIFs of crack tips. Originality/value New analytical dislocation solution in an FGM coating-substrate system is developed.

“…Wang and Han (2010) obtained the mechanical, electric, and magnetic fields in the cracked magneto-electro-elastic laminate by the singular integral method. Li et al (2011) employed the Hankel transform technique to study a flat annular interfacial crack between dissimilar MEE layers under mechanical, electric, and magnetic loadings, in which the magnetoelectrically impermeable boundary condition on the crack surface was adopted. Huang et al (2009) had been given the solution of an impermeable interface crack in dissimilar MEE media by making use of the Stroh formalism.…”

The mode III interface crack between two dissimilar magnetoelectroelastic materials is studied by means of symplectic expansion. Four crack surface electromagnetic assumptions, that is, electrically and magnetically permeable, electrically permeable and magnetically impermeable, electrically impermeable and magnetically permeable, and electrically and magnetically impermeable, are taken into account. In the symplectic space, stress, electric displacement, and magnetic induction are found to be the dual variables of the displacement, electric potential, and magnetic potential. The Hamiltonian governing equations that allow the use of the method of separation of variables are formulated by employing the variational principle of mixed energy. Expressions for the mechanical, electric, and magnetic fields are derived explicitly in the series of symplectic eigensolutions with coefficients to be determined by the boundary conditions, and so are the fracture parameters, such as field intensity factors and energy release rates for dissimilar bimaterials. Numerical results are provided to verify the validity of the present method and reveal the influences of the material constants and boundary conditions.

In this paper, an interfacial penny-shaped crack between magnetoelectroelastic thin film and elastic substrate subjected to mechanical and electric loads is investigated. Four kinds of crack-face magnetoelectrically boundary conditions are adopted. Using Hankel transform technique, the mixed boundary value problem is reduced to a system of singular integral equations. The integral equations are further reduced to a system of algebraic equations with the aid of Jacobi polynomials. The stress intensity factor and energy release rate are determined. Numerical results reveal the effects of electric and magnetic loadings, magnetoelectroelastic boundary conditions and material parameters of composite on crack propagation and growth. The results seem useful for design of the magnetoelectroelastic composite structures and devices of high performance.
