Unformatted text preview: =dilatation (% change in volume) For element subjected to uniform hydrostatic pressure, Subjected to uniform pressure, dilatation must be negative, therefore Shearing Strain shear strain is quantified in terms of the change in angle between the sides: Reduction of the angle between two sides ==> + shear stress is the change in angle (radian) Hookes law for shearing stress and strain (small strain): G : modulus of rigidity or shear modulus . E/3 < G < E/2 Shearing Strain cont. Generalized Hookes Law Relation Among E , , and G Components of normal and shear strain are related, Axial load results in both normal and shear strain. 2.71 2.77...
