http://www.ce.memphis.edu/4135/PDF/Notes/Chap_8_1_T-beam.pdf WebShear strength of a soil is indicative of its resistance to erosion. Specifically, it is defined as the resistance to deformation by the action of tangential (shear) stress. Soil shear strength is made up of cohesion between particles and resistance of particles sliding over each other due to friction or interlocking.
