Webangle of internal friction (friction angle) A measure of the ability of a unit of rock or soil to withstand a shear stress.It is the angle (φ), measured between the normal force (N) and resultant force (R), that is attained when failure just occurs in response to a shearing stress (S).Its tangent (S/N) is the coefficient of sliding friction.Its value is determined … WebIn soil mechanics, the shear strength is evaluated using the Mohr-Coulomb (M-C) Failure Criterion. The M-C Criterion assumes that the shear strength depends on three factors: The normal effective stress (σ n) The friction angle of the material (φ) The cohesion of the material (c) The qualitative correlation of those components is expressed as:
