Direct Shear Test for Shear Strength of Soil - Civil Engineering

Apr 13, 2021  13/04/2021 by vicky. The most common method of shear testing is the direct shear test. It includes pushing a soil specimen to fail along a predetermined shear plane and testing the resistance to deformation. The Mohr-Coulomb law of shearing strength is based on a relationship between shear stresses and normal stresses on a horizontal slip plane.
