| Abstract: | In this paper,the equations of the plastic deformation and mechanics of the inverting process are derivde; From the equations, a numerical method based on the incremental strain theory for simulation of the process is given. With the help of the method, a comprehensive investigation of the effect of various factors on the inverting can be made. The behaviour of the stress-strain distrbutions of the inverting is searched. The result of load-shortening curve obtained by simulation is consistent with the experimental result. The achievements of this study may serve as a significant guide to the practice of the relevant processes. |
