Finite Element Analysis of Cross-Wedge Rolling Process
Dinh Van Hai,Dao Minh Ngung,Nguyen Trong Giang 한국소성가공학회 2010 기타자료 Vol.2010 No.6
In this study, a non-isothermal simulation model for flat-wedged cross-wedge rolling (CWR) to fabricate a bullet was presented by using three-dimensional thermo-rigid-plastic finite element method (FEM). Both deformation behavior and heat transfer of the process were taken into account. Based on the simulation results, the distributions of temperature, stress, strain areas were analyzed. These results could provide theoretical guidance for net shape and reasonable design of tools.
