Dynamic stress analysis of scattering by a circular cavity in a radially inhomogeneous unbounded space under SH waves

Abstract The density of a radially inhomogeneous unbounded space is derived as function form. Harmonic dynamics stress the medium with circular cavity investigated by complex variable method. governing equation under incident SH waves in expressed Helmholtz coefficient. It equivalently transformed into standard conformal transformation Then, fields can be proposed. results indicate that changes parameter and wave number further affect dynamic concentration factor around cavity.
