The presented model is based on an appropriate interaction of a displacement field and a velocity field. The constitutive equations and the applied algorithm are developed from the exact solution for a standard case. The standard case evolves from a very tall vertical plane strain silo containing material that flows at a constant speed. No horizontal displacements and velocities take place. No changes regarding the field values arise in the vertical direction and in time. Tension is not allowed at any point. Coulomb friction represents the effects of the vertical walls. The interaction between the flowing material and the walls is covered by a forced boundary condition resulting in an additional matrix for the solid component as well as for the liquid component. The resulting integral equations are designed to be solved directly. Three coefficients describe the properties of the granular material. They govern elastic solid behavior in combination with viscous liquid behavior. 4950 https://doi.org/10.25643/bauhaus-universitaet.2959$xR$3Volltext$534 4950 https://nbn-resolving.org/urn:nbn:de:gbv:wim2-20170327-29596$xR$3Volltext$534 4961 https://www.db-thueringen.de/receive/dbt_mods_00037192 5051 510 5550 Architektur 5550 CAD 5550 Computerunterstütztes Verfahren
