Abstract
An integral formulation for 2D cracked infinite anisotropic magneto-electro-elastic media is presented. Based on the method proposed by Garcia-Sanchez et al. (Comput Struct 83: 804-820, 2005), the hypersingular kernels are analytically transformed into weakly singular and regular integrals with known analytical solution. Special quadratic discontinuous crack tip elements are employed to model the singular characteristics of the stresses, electric displacements and magnetic inductions. The extended stress intensity factors at the crack tips are calculated using the extended discontinuous displacements at crack tip elements based on one point extended displacement formulation. Some results for curved cracks in magneto-electro-elastic media are also presented.
