摘要：
Based on complex function theory and conformal transformation method, the problem of circular hole scattering in infinite inhomogeneous medium is solved, the heterogeneity of the medium is reflected in the fact that the shear modulus is variable and the density is constant,Under the condition of time-harmonic, The complex governing equation can be simplified to Helmholtz equation with variable coefficients by introducing a displacement transformation expression, Then the Helmholtz equation with variable coefficients is standardized by conformal transformation method,and the stress and displacement field around the circular hole are obtained in the complex coordinate system.
