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. i petty the fool bandWebIf the block on the far side of the fault moves to the left, as shown in this animation, the fault is called left-lateral (Figure 2).
