NEW STRATEGY IN SOLVING INVERSE SCATTERING PROBLEMS OF ELASTIC WAVES

SHI WenPu1 LI CuiHua2 ZHANG ChunPing1 FANG ShiJie1 XU QinHua1(1.College of Electro-Mechanical and Engineering,Yantai University,Yantai 264005,China)(2.Educational Administration,Yantai Training College of High Mechanic,Yantai 264006,China)  
An new optimization method in solving the inverse SH(shearing horizontal)-wave scattering problems of the half circular cavity on the boundary of the half space and the circular cavity shallow-embedded in the half space was put forward.The model and characteristics of the two kinds of inverse problems of the elastic waves were analyzed concretely,the optimization objective function and the inverse mathematical model are given,the golden section method or the half-division method was used to solve the inverse problems,the results of the given examples show the feasibility of the method.This method has application value and theoretical instruction meaning to the solution of the inverse scattering problems of elastic waves which positive problems are well studied.
