.... The article summarizes the general process of distortion failure analysis. It also discusses three types of distortion failures that provide useful insights into the problems of analyzing unusual mechanisms of distortion. These include elastic distortion, ratcheting, and inelastic cyclic buckling...

... for aluminum alloy 2014-T6 and the hardness surpassed the minimum hardness required for aluminum alloy 2014-T6. An abrupt change in the direction of grain flow across the fracture plane indicated that the wall had buckled during forging. This evidence supported the conclusion that the wheel half failed...

Limit analysis assumes an idealized material—one that behaves elastically up to a certain yield strength, then does not work harden but undergoes an indefinite amount of plastic deformation with no change in stress. The inherent...
