... pressure and consequently will cause changes to the effective stress, traction and elastic properties. The main purpose of this study is to examine the effect of pore pressure changes on seismic wave propagation (i.e. amplitude, frequency range). This is achieved by using a dual simulation of fluid flow...

... for discontinuities in the displacement field. Since the inception of DGM for seismic wave propagation in fractured media there has existed a question of whether DGM can be made computationally efficient. Here we propose a Hybrid Galerkin FEM (HGM) for elastic wave propagation in fractured media. HGM combines SEM...
