Shear strength

ratio of shear stress to the shear strain

component of stress coplanar with a material cross section

(of a granular material) steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding

mathematical model describing the response of a brittle material to mechanical stresses and to define shear strength of soils and rocks

strength of a material or component against the type of yield or structural failure when the material or component fails in shear

part of shear strength that is independent of the normal effective stress in mass movements

Magnitude of the shear stress that a soil can sustain
