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