Abstract:

The thin cylinder under step deformation path of tension and torsion based on YU Mao-hong unified strength theory was analyzed. The unified incremental solution was obtained and it could be applied to various materials with strength difference effect. It is applied to all kinds of ideal elasto-plastic materials with different ratios of tension and pressure and makes up the shortage that a special material should select a corresponding yield rule. According to it, different stress states and tracks of yielded ideal elasto-plastic material become easy to be simulated by computer. The results show that by altering the material synthesis influencing coefficient, the POISSON's ratio, the ratio of tension and pressure and the coefficient which represents influence of shearing stress, people can use only a few materials to imitate the yielded property of other materials known or unknown.
