The equivalent stress-equivalent strain curves for both tension and torsion specimens are shown in Fig. 1. The use of equivalent stress-strain allows comparison between the two types of testing. In both cases, the curves are characterized by an initial rise in stress with strain up to about ε e = 50%.

WebFor a small stress, the relation between stress and strain is linear. The elastic modulus is the proportionality constant in this linear relation. Tensile (or compressive) strain is the response of an object or medium to tensile (or compressive) stress. Here, the elastic modulus is called Young’s modulus. WebShear Stress, Strain, and Modulus.

Measure the original length of the work piece. Apply shear stress on the material. Measure the angle of deformation. tan of angle of deformation gives the shear strain.

Strain represents the displacement between particles in the body relative to a reference length. Deformation of a body is expressed in the form x = F(X) where X is the reference position of material points of the body. Such a measure does not distinguish between rigid body motions (translations and rotations) and chang…
