Development of a Contact Model for Analyzing a 2-D Elastic–Plastic Reshaping Process of Pipes
Abstract:   (5662 Views)
Predicting the status of contact between the pipe and the roll through deformation is considered as one of the problems of reshaping process in non-circular pipe production. In the present study, the elastic-plastic analysis is investigated assuming plane strain condition for reshaping process. One of the problems of the mentioned process is the separation of pipe from roll in some zones. The proposed model has the capability of predicting the separation of the pipe from roll, which results in better prediction of the defect. To verify the reliability of the present contact model, the result of the analysis was compared to those of experimental ones and showed good agreements.
