Finite Element Modeling of External Inversion and Comparison of Results with Existed Experimental and Theoretical Results

Abstract

The objective of this paper is to simulate inversion process and prediction of proper parameter to perform process successfully. This research present an investigation of the external inversion of tubes by using available commercial numerical codes. The numerical investigation is verified and assessed by means of existing analytical and experimental results. The numerical results have been compared with existing empirical and analytical results, so the ability of numerical codes to predict the required force to perform the inversion process of the tubes has been examined. The theoretical results correlate well with those obtained through experiments. Finally by use of numerical results and their validation using existing experimental results, a method is available in order to help to predict geometry and loading conditions under which the process is conducted successful.
