Abstract: The hollow composite cylinder consisting of an inner orthotropic functionally graded elastic substrate and an outer orthotropic functionally graded elastic layer with cyclically symmetric cracks is considered under an anti-plane shear load.The method of variable separation is employed to reduce this mixed boundary value problem to a Cauchy singular integral equation,which is solved numerically by the Lobatto-Chebyshev quadrature technique,then the numerical results for the stress intensity factor are obtained.The effects of the graded parameters,geometrical and material constants on the stress intensity factors are discussed.
