Pore Pressures in Simple Shear
Soils and Foundations, 1986 ABSTRACT Measurements made of the changing stress state during a constant volume simple shear test on kaolin permit the implied pore pressure change to be divided into a component due to change in total mean stress and a component due to dilatancy of the soil.
