The major principle stress at failure for a triaxial compression test on dense sand was 5.15
tsf.the minor principal stress ,or lateral pressure, was 1.45 tsf. Plot the mohr circle at failure
and, assuming the sand to be cohesionless, determine the angle of internal friction.
Solution
Since, the data for major and minor principal stresses are known, the next step is to plot the
mohr’s circle and determine graphically the angle of...
