Question: The effective stresses at failure for three identical triaxial specimens of an over-consolidated clay are shown in Fig. P13.49. Plot the Mohr circles at failure

The effective stresses at failure for three identical triaxial specimens of an over-consolidated clay are shown in Fig. P13.49. Plot the Mohr circles at failure and determine âˆ…' and c'. Determine the theoretical angle of inclination of the failure planes in each test specimen, and show these on a small sketch. Also sketch the effective stress paths for the three tests. (After C.W. Lovell.)?
