Abstract: The methods of complex function, multi-polar coordinate system, andconformal mapping are used to solve dynamic stress concentration factor. The surface elasticity theory is applied to obtainthe stress boundary conditions on the surface. The effects of frequency and theration of the major and minor axis of the ellipse on the dynamic stressconcentration factor around the elliptical nano-hole are discussed in detail.When the size of elliptical hole shrinksto nanometers, the numerical results show that the surface effect has asignificant effect on the scattering of SH-wave.
