"Novel Phenomena in Capillary Driven Deformation of Porous Structure "

ABSTRACT


A brief review of problems related to non-Newtonian fluid mechanics at P∓G will be provided. A more in depth presentation of recent research in the area of capillary driven deformation of hyperelastic porous media will be the primary topic. New materials with very high porosity and tunable elastic moduli enable exploration of material behavior in regions where capillary pressures play a large part in deformation. We have discovered novel phenomena such as biphasic volumetric strains in partially saturated porous media and will demonstrate a theoretical model that predicts this phenonena.
