Keywords: Anti-plane elastodynamics, Magnetoelectroelasticity, Nano-crack, Gurtin-Murdoch model, Wave diffraction and scattering, SCF, BIEM.
Abstract: Anti-plane elastodynamic problem for shear (SH) wave scattering and diffraction by a nano-crack in a magnetoelectroelastic (MEE) plane is solved herein. The presencppppe of a nano-fracture within the MEE matrix gives rise to both wave scattering and stress concentration phenomena, the latter being responsible for fracture of the magnetoelectroelastic solid. The proposed model takes into consideration the surface/interface properties, the size of the nano-crack and the interaction between the crack, incident wave and the multifunctional MEE matrix. The method of solution is the boundary integral equation method (BIEM), which is first verified against benchmark examples and subsequently applied for numerical simulations. The BIEM formulation combines classical elastodynamic theory for the bulk solid with non-classical boundary conditions and the localized constitutive law for the matrix/nanocrack interface within the framework of the Gurtin-Murdoch theory..
