The Relationship between Constant Friction Factor and Coefficient of Friction in Metal Forming using Finite Element Analysis
Frictional shear stress is usually determined by utilizing the coefficient of friction or the constant friction factor models. The present study deals with finite element analysis of double cup extrusion process to determine the relationship between constant friction factor (m) and coefficient of friction (µ), since the metal flow in this process is very sensitive to frictional conditions. Ther...
متن کاملA Review on Finite Element Simulations in Metal Forming
Finite element simulations are often required to reduce the experimental cost and time by reducing number of trials in the product development cycle. Metal forming is one of such area where a lot of trials are required to arrive at the die design to produce defect free parts. Hence in this paper the authors review the literature on finite element analysis in the area of metal forming
متن کاملApplication of Finite Element Simulation in Metal Forming Tribology
The impact of numerical methods, particularly, the Finite Element Method (FEM), in providing tribological information relevant for lubricant formulations and general study of tribological variables is discussed. FEA was used to study surface evolution at the tool-workpiece interface for tube hydroforming and forging processes. The study has demonstrated that material properties, geometric compl...

متن کاملDetermination of Buckling Limit of Strain in Cold Roll Forming through Finite Element Analysis
In this study, Buckling Limit of Strain (B.L.S.) is introduced as one of the most important limiting factors in cold roll forming process. B.L.S. is calculated by the finite element procedure. Then for two particular processes with existing analysis and experimental results, B.L.S. has been determined and evaluated. LUSAS 12.3 is used for finite element analysis. The results show that when buck...
