11-88. A normally consolidated clay has a p' of 30°. Two identical specimens of this clay are consolidated to 200 kPa in a triaxial cell. Predict the maximum and minimum possible axial stresses in the specimens for a constant cell pressure. Hint: The .first test is an axial compression test, the second test is an axial extension test. What assumptions are necessary to solve this problem?
