Question

Total number of stress components at a point within a soil mass loaded at its boundary is

Answer 1

The correct answer is six.

• The main problem in a geotechnical study is the approximation of the state of stress at a point at a specific depth in a soil mass.

• If we reflect an elemental cube of soil at the point measured then a solution by elastic theory is conceivable. Each plane of the cube is exposed to stress, a, acting normal to the plane, along with shear stress, r, standing parallel to the plane. So, a total of six stress components acting on the cube
