【Abstract】 In this paper the formula of work of plastic deformation and the 3-dimensions figure of Twin shear stress yield criterion in the plane stress condition are derived. The limited loads of a simply supported circular plate subjected to uniform load and a thick-walled tube under the action of an internal pressure and axial force are exactly resolved by upper and lower bounds. The calculated results are compared with that in Mises and Tresca criterions.更多还原
