| Abstract: | At first,the bending-load process of steel pipe is analyzed for the mechanical bending manufacture in normal cold condition.After rebounding the residual stress is assumed to be in equilibrium state,and the distorted section is still remained in harmonious plane,the analytic model is thus developed for the distribution of the residual stress in the section.The resilience radius and rebound moment are formulated further.And some parametric analysis is completed.Finally,a series conclusions are summarized,it is valuable for the engineer to design and manufacture of the practical projects. |
