WebHowever, we are handicapped by the geological variability of soils and methods for obtaining reliable values of shear strength. The analyses of slope stability are based on simplifying assumptions, and the design of a … Webshear stress, force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress. The resultant shear is of great importance in nature, being intimately related to the downslope movement of earth materials and to earthquakes. Shear stress may occur in solids or liquids; in the latter it is related to fluid viscosity.
