WebMar 26, 2024 · The Tresca criterion is one of the most basic failure theory suitable for ductile materials. It predicts that the material will fail, when the maximum shear stress … WebThis could cause failure too. The beam has a potential to fail in shear. The force acting downward, if the beam doesn't have enough shear resistance to resist that upward, you will get failure, or it could fail in bending. These long slender beams tend to fail in bending. Bending will dominate their behavior.
