1.	In the yield criteria of metal, von-mises criteria are also known as distortion energy theory.(a) True(b) FalseThis question was posed to me during a job interview.The question is from Plastic Deformation and Yield Criteria in section Types of Die & Metal Forming Processes of Casting-Forming-Welding II
Answer» Correct choice is (a) True The EXPLANATION is: In the yield criteria of any metal, von-mises criterion is also known as distortion ENERGY THEORY. This theory shows that the plastic DEFORMATION of metal occurs when the value of shear STRAIN energy per unit volume of the body becomes equals to the strain energy per unit volume at the elastic limit of the metal.
