Soil shear

WebSoil shear strength is made up of cohesion between particles and resistance of particles sliding over each other due to friction or interlocking. Cohesion is composed of true cohesion and apparent cohesion. True cohesion is a function of soil mineralogy and results from chemical bonds between particles.
