Web28 de out. de 2024 · Shear strain is the measure of shear deformation caused due to shear stress. It indicates the change in the shape of the object and it is denoted by the symbol … 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.
