Stress field near circular-arc interface crack tip based on electric saturation concept

Longchao DAI, Xinwei WANG

Frontiers of Mechanical Engineering 2009, Volume 4, Issue 3,   Pages 320-325 doi: 10.1007/s11465-009-0042-9

Abstract: Within the framework of nonlinear electroelasticity, the anti-plane problem of a circular-arc interfacial crack between a circular piezoelectric inhomogeneity and an infinite piezoelectric matrix subjected to a far-field uniform loading is investigated by an electrical strip saturation model, the complex variable method, and the method of analytical continuation. Explicit closed form expressions for the complex potentials in both the matrix and the inclusion, and the stress intensity factor at the crack tip are presented. Comparison with some related solutions based on the linear electroelastic theory shows the validity of the present solutions
