Application returned Rvshngasht Kshsanykhmyry analysis of pressure vessels with non-linear behavior of hard Kinematics

Elastic plastic analysis of pressure vessels has an important role in their design. To do this analysis using a suitable computational method is necessary. "Backward mapping" A computational method is suitable for analyzing nonlinear problems. In this study using this method a cylinder under internal pressure to change Jdarzkhym Elastic paste form has been analysis. Material behavior, nonlinear with Skhtshvndgy Kinematics is assumed. Frederick Armstrong model to express the basic equations and give Fvnmyss criteria were used to evaluate the behavior of matter. Equations using mapping method extends back to the above behavior analysis Jdarzkhym cylinders, stress strain diagrams were determined Dvrhyy structures under loading. Compare the results with finite element results indicate compliance technique caused considerable these results.
