Abstract: Methodologies of rapidly assessing maximum possible forming heights are needed for three-dimensional (3D) sheet metal forming processes at the preliminary design stage. In our previous work, we ...

Abstract: Excessive coil deformation can complicate normal handling of a wound or rolled coil, cause difficulties in mass production, and introduce undesirable variations in the subsequent manufacturing ...

Abstract: Thin-walled tube bending has found many of its applications in the automobile and aerospace industries. This paper presents an energy approach to provide the minimum bending radius, which does ...

Abstract: Tailor Welded Blanks (TWBs) offer several notable benefits including decreased part weight, reduced manufacturing costs, increased environmental friendliness, and improved dimensional consistency. In ...

Abstract: Flanging is a commonly used sheet forming operation to increase the stiffness of a sheet panel and/or to create the mating surface for subsequent assemblies. This paper presents an energy ...

Abstract: A wedge strip test is designed to study the onset and post-buckling behavior of a sheet under various boundary constraints. The device can be easily incorporated into a conventional tensile ...

Abstract: Sheet metal forming is one of the most important and frequently used manufacturing processes in industry today. One of the key parameters affecting the forming process is the blank holder force ...

Abstract: One of the greatest challenges of manufacturing sheet metal parts is to obtain consistent part dimensions. Springback, the elastic material recovery when the tooling is removed, is the major ...

Abstract: Incremental forming (IF) of sheet metal is emerging as a useful flexible manufacturing process for forming customized shapes, some of which may not be formable using conventional techniques due ...
