heal.abstract	Internal erosion processes in geomaterials like fluid-saturated sand-gravel layers play a significant role in geotechnical and petroleum engineering. We suggest a general modeling framework within such a solid-liquid phase transition phenomenon can be described. The phenomenological continuum-based model is formulated within the thermodynamically-consistent Theory of Porous Media. The mixture consists of four constituents. Furthermore, mass exchange between a solid and a liquid phase is taken into account. The hydromechanically-driven erosion process is mainly described by the constitutive equation of mass production. The degradation of the stiffness of the solid skeleton is taken into account by a damage-like behavior.	en
