Mohr-Coulomb Failure Envelope
A material's strength may be assumed to be governed by the Mohr-Coulomb failure envelope...
Where 
is the shear strength of the material, 
is the cohesion, and 
is the friction angle.
Definitions
- friction angle
- the maximum angle at which the soil material can hold in place
