Webresidual stress. Under very low loads, deformation is found to be proportional to stress. The case of linear continuum elasticity is the main subject of this article. First, the foundations of stress and strain are laid out in the inﬁnitesimal limit. Then simple forms of the elastic equations for isotropic bodies are introduced using Web4.a An elemental cube is subjected to tensile stresses of 30 N/mm² and 10 N/mm² acting on two mutually perpendicular planes and a shear stress of 10 n/mm² on these planes. Draw the Mohr's circle of stresses and hence determine the magnitudes and directions of principal stresses and also the greatest shear stress.
