WebThe results of the tests on each specimen are plotted on a graph with the peak (or residual) stress on the y-axis and the confining stress on the x-axis. The y-intercept of the curve which fits the test results is the cohesion, and the slope of the line or curve is the friction angle. Direct shear tests can be performed under several conditions. Web• A conventional triaxial compression (CTC) test is run on a loose sand with a friction angle of 20. The cell pressure is 30 psi. Determine the following: – The orientation of the failure plane – The stresses acting on the failure plane at failure – The axial stress at failure – The stress path corresponding to this test
