Schemes in generalized finite differences for seismic wave propagation in Kelvin-Voight viscoelastic media

摘要

Seismic wave propagation in homogeneous and isotropic Kelvin Voight viscoelastic media is dealt with the mesh less generalized finite difference method. The schemes in generalized finite differences for the decoupled system P-SV and SH are obtained. For each scheme, a stability limit is achieved and the star dispersion is calculated. Some cases are shown using irregular discretizations.
