WebIn rocks or rock-like materials, the constituents, e.g. quartz, calcite and biotite, as well as the microdefects have considerably different mechanical properties that make such materials heterogeneous at different degrees. The failure of materials subjected to external loads is a cracking process accompanied with stress redistribution due to material heterogeneity. … WebThe angle of internal friction of a cohesive soil which was tested using a tri-axial shear apparatus is equal to 26.57 degrees. Failure occurred when the shearing stress is 250 kPa and the normal stress is 480 kPa. Determine the maximum principal stress at failure in kPa, deviator stress at failure in kPa, and cohesion of the soil in kPa.
