Unified Stresses Solution for Sheet Forming

摘要：

Based on unified strength theory,the unified stresses solution for sheet forming is presented according to mechanical analysis developed,and accurate enough for much material due to the contributions of both intermediate principal shear stress and varying tension-compression-ratio included.Notably,by denoting a notation of h,the expressions presented to estimate stresses of billet for sheet forming can be apply to both drawing and extrusion.In addition,when material has identical strength in tension and compression,i.e.,the tension-compression-ratio of the material is equal to unit,the stresses solution based on unified strength theory become that based on unified yield criterion.Accordingly,it can be proved that the stresses solution based on Mises criterion is just a special case of that based on unified yield criterion.
