The shear Modulus of elasticity is one of the measures of the mechanical properties of solids. Other elastic moduli are Young’s modulus and bulk modulus. The shear modulus of material gives us the ratio of shear stress to shear strain in a body. Measured using the SI unit pascal or Pa. The dimensional formula of shear modulus is M 1 L-1 T-2.A torsion test is a mechanical testing method that evaluates the properties of materials or devices under stress caused by angular displacement. During a torsion test, a specimen is subjected to a twisting or torsional force, which induces a torque. This test is used to measure various mechanical properties of materials, including their modulus of rigidity, shear stress, .Torsional rigidity = G x J. Thus, it depends on the shear modulus (G) and polar moment of inertia (J) of the object. Let’s discuss, how these factors affect torsional rigidity. 1] Higher Shear Modulus Means Greater Torsional Rigidity: The below figure shows two objects of the same size made with a material having different shear moduli. When .torsional load when a material breaks. While the modulus of rigidity shows the size of the stiffness of a material in its elastic region. In torsion tests, the value of the modulus of rigidity is obtained through the comparison of shear stress with shear strain that occurs in the elastic region. Figure 1: Dimensions of torsion test specimens 3.
