Abstract
The paper deals with development, verification and application in simulations of an efficient non-hypersingular traction boundary integral equation method (BIEM) for solution of boundary-value problem (BVP) describing time-harmonic SH-wave scattering by two impermeable nanocracks in an exponentially graded anisotropic piezoelectric plane. The modeling approach is based on the surface elasticity continuum model proposed by Gurtin and Murdoch and linear fracture mechanics. The sensitivity of the stress and electric concentration factors to the electromechanical coupling, to the characteristics of the incident wave, to the position-dependent material properties, to the surface elasticity and to the dynamic cracks interactions is presented and discussed.
