Finite Element Modelling of Forging and Other Metal Forming Processes
The fundamental mechanical formulation is recalled for simulation of metal forming processes. The basic principles of 3-dimensional finite element discretization and of time integration are summarized. Several important numerical developments for efficient computation of large plastic deformation are briefly described. Various fields of applications to real processes are reviewed. Illustrative ...
متن کاملApplication of the Finite Element Method In Cold Forging Processes
The demand for more efficient manufacturing processes has been increasing in the last few years. The cold forging process is presented as a possible solution, because it allows the production of parts with a good surface finish and with good mechanical properties. Nevertheless, the cold forming sequence design is very empirical and it is based on the designer experience. The computational model...
متن کاملDimpling process in cold roll metal forming by finite element modelling and experimental validation
The dimpling process is a novel cold-roll forming process that involves dimpling of a rolled flat strip prior to the roll forming operation. This is a process undertaken to enhance the material properties and subsequent products' structural performance while maintaining a minimum strip thickness. In order to understand the complex and interrelated nonlinear changes in contact, geometry and mate...
متن کاملRigid-plastic finite-element analysis of sheet-metal forming processes using a selective membrane/shell formulation
In most sheet-metal forming processes a large part of the deforming material exhibits stretch-dominant characteristics and the bending effect is found to exist only in a limited portion of the total deforming region. Thus the use of shell or continuum elements for the whole region is not economic. A selective membrane/shell (M/S) scheme is proposed which combines the layered degenerated shell e...
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...
