In the present work, a so‐called hybrid two‐phase model composed of a materially incompressible solid and a compressible pore fluid is studied. The mechanical behavior is described by the thermodynamically consistent Theory of Porous Media (TPM). Numerical experiments were performed with the space‐time coupled discontinuous galerkin (DGT)‐method. The existence of two compressional waves (P‐waves) and one shear wave (S‐wave) was confirmed.
