A displacement field a pressure field and a velocity field describe the behavior of hybrid materials that is not covered by a single solid or liquid state approach. A primary analysis that is represented by a functional and its associated principle is based on a two states analysis consisting of a solid part and a pressure part. The pressure part is related to a velocity field in a secondary analysis. With respect to granulates the interaction at the walls is directed towards the avoidance of tension. Equilibrium is achieved separately for area and boundary. The distribution of the specific weight on solid and liquid parts depends on the first stress invariants.
