Additional Failure Criteria
Octahedral Shear Stress Yield Criteria: This is another yield criteria often used for ductile metals. It states that yielding occurs when the shear stress on the octahedral planes reaches a critical value.
Mohr-Coulomb Failure Criterion: This is used for brittle metals, and is a modified Tresca criterion.
Griffith Failure Criterion: Another criterion used for brittle metals. It simply states that failure will occur when the tensile stress tangential to an ellipsoidal cavity and at the cavity surface reaches a critical level ?0.
