Direct Shear
A direct shear test is a geotechnical laboratory procedure to measure the shear strength of soil by applying a normal load to a soil sample and then shearing it horizontally across a predetermined plane until failure. The test determines the soil’s cohesion (C) and angle of internal friction (Ø), which are critical parameters for designing structures like foundations and retaining walls. The soil sample is contained in a two-part shear box, and the upper half is moved horizontally relative to the fixed lower half, while the shear force and horizontal displacement are measured until the sample fails.
