Dynamic Lattice Method for Elastic Wave Simulation in 3-dimensional Arbitrary Anisotropic Media
View through CrossRef
To simulate the elastic wave propagations in 3-dimensional (3D)
anisotropic media, a 3D anisotropic lattice model is proposed. The
derivation of the general relationship between the anisotropic lattice
model and the anisotropic continuum model is presented. With this
lattice model, the dynamic lattice method (DLM) is able to simulate
elastic wave propagation in arbitrary anisotropic media. Numerical tests
on different anisotropic models show that the elastic waves simulated by
the DLM coincide with those simulated by the finite difference method,
indicating that the dynamic lattice method represents a lattice-based
choice for the elastic wave simulation in complex anisotropic media. Our
research demonstrates the robustness of the anisotropic lattice model in
describing anisotropic media, and lays the foundation for lattice-based
methods in terms of elastic wave modeling in 3D anisotropic media.
