Determining the Optimal Yield Radius and Optimal Pressure of Autofrettage of Curved Elements of Pipelines and Pipes

Abstract

Formulas for calculating the optimal yield radius and optimal pressure of autofrettage of curved elements of pipelines obtained as a result of a solution of an elasto-plastic problem are presented. Formulas for calculating the optimal yield radius and optimal pressure of autofrettage of pipes as well as results of calculations using the proposed formulas and a comparison of the results with the actual values of the pressure of autofrettage of pipes are presented.
