1 The shear modulus or modulus of rigidity 2  (. or) describes an object's tendency to shear (the deformation of shape at constant volume) when acted upon by opposing forces; it is defined as shear stress over shear strain. Young's modulus 2  (. ) describes tensile elasticity, or the tendency of an object to deform along an axis when opposing forces are applied along that axis; it is defined as the ratio of tensile stress to tensile strain. 3  It is often referred to simply as the elastic modulus. 4  The shear modulus or modulus of rigidity (.
