Shear stress. In physics, shear stress is a stress state in which the shape of a material tends to change (usually by "sliding" forces -- torque by transversely-acting forces) without particular volume change.
shear stress is the shear strength of the soil for the particular value of the normal force N or normal stress (N/A) applied to the soil, where A is the cross sectional area of the soil sample. Fig. 8.8 shows that a dense sand has a greater shear strength than a loose sand and this strength is reached at a smaller value of the displacement.
See full list on engineeringtoolbox.com shearing stress - stress that tends to shear the material - acts in plane to the stressed area at right-angles to compressive or tensile stress. Tensile modulus is often used for plastics and is expressed in terms 105 lbf/in2 or GPa. Shear Modulus of Elasticity - or Modulus of Rigidity.
The shear stress at the peak is known as peak shear strength. After reaching the peak value both the curve show a decrease in shear stress and reach the same constant ultimate shear stress. This is known as residual strength or ultimate shear strength. The sand in loose condition also tends to reach the same ultimate shear strength.
