The **Mohr-Coulomb Failure Criterion** represents the linear envelope that is obtained from a plot of the shear strength of a material versus the applied normal stress. This relation is expressed: `tau=sigmatanphi+c`, where:

- `sigma` = normal stress
- `phi` = slope of the failure envelope
- `c` = intercept of the failure envelope (cohesion)
