WebA new finite‐difference (FD) method is presented for modeling SH-wave propagation in a generally heterogeneous medium. This method uses both velocity and stress in a discrete grid. Density and shear modulus are similarly discretized, avoiding any spatial smoothing. Therefore, boundaries will be correctly modeled under an implicit formulation. Standard … The energy density carried by seismic waves can be expressed as a sum between the kinetic energy density (K) and the potential energy density (W ), as E = K + W while K, as usual, can be written as the derivation of W (strain energy functional), is classically based on mechanical and thermodynamic considerations (Aki and … See more Within this work all of the tests use a source located at the center of the fault zone at the same distance with respect to the left and right fault boundary.
