Failure Theories — Max-Shear (Tresca) & Von Mises
Inside this lesson
- State the Tresca (maximum shear stress) yield criterion and compute the equivalent stress
- State the von Mises (distortion energy) criterion and compute the equivalent stress
- Compare the conservatism of Tresca vs von Mises for the same stress state
- Briefly identify the appropriate brittle-material criterion (maximum normal stress)
