Study on Thickness Distribution and Spring Back Phenomena of Sheet-Bulk Forming for Aluminum Alloy

Abstract:

With the advance of technology, aluminum alloy has been widely used in industry. In this study, the formability and spring back phenomena of thick aluminum alloy sheet metal were investigated. Deform-3D and Simufact.forming software were used to simulate the sheet-bulk forming. To find the optimal element size, the convergence analysis method for mesh of simulation process was utilized. In addition, thickness distribution and spring back phenomena of the rectangular blank with round feature of corners were also evaluated. Simulation results were compared to scanning file that obtained via ATOS based on spring back phenomena from experiments. Study results show that the optimal element size is 2 mm. The cross section that is near binder area in x-direction and near quarter area of laptop keyboard in y-direction has minimum spring back. Solid-shell element is better than tetrahedral element for analyzing sheet bulk metal forming process.
