Towards understanding coupled fluid-granular deformation during shear Conference Paper uri icon


  • Abstract The deformation of coupled fluid-granular matter is a fundamental physical problem, with many practical implications: from shearing of a fluid-filled gouge zone, to earthquake induced liquefaction, and to formation of debris flows. The basic picture is a porous skeleton made of contacting grains, with fluid-filled pores. The skeleton may deform elastically or in a poro-plastic manner (eg pore collapse). Such changes of pore structure and volume may affect the pore fluid pressure. The fluid pressure in turn exerts a force …
