Hybrid modeling of elastic-wave propagation in two-dimensional laterally inhomogeneous media

摘要: We have constructed a hybrid scheme for elastic‐wave propagation in two‐dimensional laterally inhomogeneous media. The algorithm is based on combination of finite‐difference techniques and the boundary integral equation method. It involves dedicated application each two methods to specific domains model structure; are applied calculate set values (wave field stress field) vicinity heterogeneous domain. continuation near‐field response then calculated by means In numerical example, method has been plane‐wave an elastic lens embedded homogeneous environment. example shows that enables more efficient modeling, with same accuracy, than pure calculations.
