Concept explainers

Test for Determination of Shear Strength

The term shear strength is often associated with the soil. Shear strength is defined as the resistance to the deformation of soil particles due to the continuous action of shear stress. In short, shear strength is the maximum shear stress that a soil can sustain.

Question

A consolidated-drained triaxial test on a normally consolidated clay yielded a friction angle, Φ', of 28°. If the all-around confining pressure during the test was 140 kN/m², what was the major principal stress at failure?
