The maximum shear stress criterion for combined direct and shear stress predicts failure when

  • A.The direct stress alone reaches yield
  • B.The shear stress alone reaches yield
  • C.The sum of the two stresses reaches yield
  • D.The principal stress difference reaches yield

Answer: D

Tresca's criterion works on the difference between the extreme principal stresses, which for combined bending and torsion produces the familiar equivalent stress expression. Von Mises gives a slightly less conservative result and is more commonly used for ductile metals.
