Elemental cube stress and strain
WebStress is force per unit surface area. Nine stress components can be defined with reference to an elemental cube (Fig. 1). The component σ ij is the force per unit area in the i direction on a face whose normal is j direction. The six components with i ≠ j are the shear stresses while the three components with i = j are the normal stresses. WebEquilibrium Equations And Stress-Strain Relations In 3D Elasticity.
