【Abstract】 The general expressions and the geometric graph of twin shear stress yield criterion in the plane problems are discussed.Combined load problem of tension and torsion of a thin-walled tube is resolved with this criterion. Its results are compared with the results which are calculated by Mises and Tresca criterion.The limited load of a simply supported circular plate subjected to uniform load is also resolved with the twin shear stress yield criterion.更多还原
