WebDec 18, 2024 · If we consider an elemental cube of soil at the point considered then a solution by elastic theory is possible. Each plane of the cube is subjected to a stress, a, … 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.
