Reflection and Transmission Problem of SH Waves in Layered Viscoelastic Medium

GUO Zhi-qi,LIU Cai,ZHANG Feng-qin(College of GeoExploration Science and Technology,Jilin University,Changchun 130026,China)  
Two chief ways are mainly used to solve the problems of viscoelasticity: one is considering the factor of viscidity in elastodynamics equation,the other is establishing models of viscoelastic medium directly from constitutive equation.The second method is mainly used because of its positivism in studying on physical appearance of medium.In this article,we firstly establish constitutive equation of convolutional forms based on Boltzman's superposition principle,and consequently establish elastodynamic equation in viscoelastic medium.After that,we obtain the solution of the equation based on which we can study on problems of reflection and transmission on interface between two viscoelastic solids.At last,we give some theoretical analysis after calculating the coefficient of reflection and transmission C_R,C_T.
