Material Behaviors
Theories of Failure
Ductile Materials:
Ductile materials always fail in shear
- Tresca's criterion (Maximum shear stress)
- Von Mises' criterion (Maximum distortion energy)
Brittle Materials:
Brittle materials always fail in tension
- Rankine's criterion (Maximum normal stress)
- Mohr's criterion
