The Integration-Interpolation Modeling of Elastic Wave Propagation in Isotropic Inhomogeneous Elastic Media

MENG Fan-shun, WANG Li, LI Qing-ren(Ocean University of China, Qingdao 266003, China)  
In this paper through the integration of the motion equation, free boundary condition and absorbing boundary condition by integration-interpolation the explicit 2D finite difference equations are respectively derived according to the Gaussian theorem. Numerical simulations are carried out for several typical models and it shows that this method is of high precision and stability.
