Direct Shear Test - University of Illinois at Chicago
cemmlab.webhost.uic.eduAug 30, 2002 · The direct shear test is one of the oldest strength tests for soils. In this laboratory, a direct shear device will be used to determine the shear strength of a cohesionless soil (i.e. angle of internal friction (f)). From the plot of the shear stress versus the horizontal displacement, the maximum shear stress is obtained for a
