Forming of Multi layer Sheet Metal by Drawing Process: an Analysis and FEM Simulation
In this paper, the drawing process of multi-layer sheet metal through wedge shaped die has been analyzed using stream function and upper bound method. Typically a sandwich sheet contains three layers of metal, where the outer layers are of the same thickness and material and different from those of the inner layer. In this study, a new deformation model has been introduced in which inlet and ou...
متن کاملA mechanics model for sheet-metal stamping using deformable dies
This paper studied the deformation mechanisms of sheet metals stamped by rigid punches and deformable dies. Emphasis was placed on the development of elastic plastic zones in the sheet workpieces, on the functions of the die parameters and on their correlations with spring-back. It was found that the reduction of spring-back was due mainly to the interface interaction offered by the dies. The p...
متن کاملIdentifying Sources of Variation in Sheet Metal Stamping
Manufacturers using traditional process control charts to monitor their sheet metal stamping processes often encounter out-of-control signals indicating that the process mean has changed. Unfortunately, a sheet metal stamping process does not have the necessary adjustability in its process variable input settings to allow adjusting the mean response in an out-of-control condition, hence the sig...
متن کاملPrediction of Instability in Planar Anisotropic Sheet Metal Forming Processes
In this paper instability of planar anisotropic sheet metal during a few forming processes is investigated for the first time. For this reason components of the constitutive tangent tensor for planar anisotropic sheets are developed. By using the above tensor location of necking is predicted. Direction of the shear band is also predicted using the acoustic tensor. A finite element program is pr...
متن کاملKnowledge Based Cloud FE Simulation of Sheet Metal Forming Processes
The use of Finite Element (FE) simulation software to adequately predict the outcome of sheet metal forming processes is crucial to enhancing the efficiency and lowering the development time of such processes, whilst reducing costs involved in trial-and-error prototyping. Recent focus on the substitution of steel components with aluminum alloy alternatives in the automotive and aerospace sector...
