WebStress is generally defined as force per unit area. When forces pull on an object and cause its elongation, like the stretching of an elastic band, we call such stress a tensile stress. … WebShear stress can be measured using various methods, including: Rheometers, apply controlled stress to a sample of the material and measure the resulting deformation or strain. Torsion tests, involve rotating a cylindrical sample of the material and measuring the torque required to maintain a constant rotation rate to calculate the shear stress.
