Mohr-Coulomb Approach

Total and effective Mohr s circles. For a specimen exhibiting positive pore water pressure, (a) Element A at failure (b) Total and effective Mohr s circles for element A at failure. 

For stress conditions associated with no lateral yielding, it might be assumed to exist. During deposition either horizontally or on a gentle inclination, may be expressed empirically

For a uniaxial compression test, determine the plane on which the maximum shear stress will occur for a material that obeys the Mohr-Coulomb yield criterion. Suggest an approach for measuring the material parameters (d>, Tq) in the Mohr-Coulomb yield criterion. (Hint construct the Mohr s circle (see Fig. 2.23) for various values of the normal stress.)...
