Abstract: Dynamic fracture behaviour of multiple anti-plane nano-cracks in infinite functionally graded magnetoelectroelastic (MEE) solid under excitation of time-harmonic SH-wave is studied. The applied approach is based on the non-hypersingular traction based boundary integral equation method (BIEM) for the graded bulk MEE solid extended with the non-classical boundary conditions and the localized constitutive law for the MEE matrix-nanocrack interface within the framework of the Gurtin-Murdoch theory. The formulation allows for an exponential variation of the material properties in an arbitrary direction. The boundary integral equation (BIE) system is treated by using the frequency dependent fundamental solution derived analytically by Fourier transforms. The numerical solution provides displacements and tractions at any point in the infinite graded solid as well as the generalized crack opening displacements from which the generalized stress concentrations are determined.
