The forming of superplastic sheet metal
International Journal of Mechanical Sciences, 1970Abstract The superplastic deformation of thin circular diaphragms subjected to onesided hydrostatic pressure is examined both theoretically and experimentally. Special attention is given to the thickness variations in bulged shapes of simple geometry (domes) and also in more complex shapes related to those encountered in practical forming operations.

Forming of Micro-sheet Metal Components
2015This chapter firstly highlights challenges in micro-sheet-metal forming and explains its characteristics and tooling design considerations. An introduction is then given to the basic processes of sheet-metal forming, emphasising, from micro-forming point of view, on the size effect, material, tooling and process capabilities.

Sheet‐Metal Forming and Assembling
Aircraft Engineering and Aerospace Technology, 1943THE modern aeroplane is constructed largely from sheet metal. As such, the most important production problems are those of sheet metal forming, and assembling. Production is here considered as not only the act of forming and assembling the required number of parts, but also the making of forming tools, and all processing of parts such as heat‐treating.

Stress-Based Forming Limits in Sheet Metal Forming
Manufacturing Engineering, 2000Abstract A strain-based forming limit criterion is widely used throughout the sheet metal forming industry to gauge the stability of the deformed material with respect to the development of a localized neck prior to fracture. This criterion is strictly valid only when the strain path is linear throughout the deformation process. There is

A courseware on sheet metal forming
Journal of Materials Processing Technology, 1994Abstract Using hypermedia concepts, an educational software on sheet metal forming has been created to run on an Apple Macintosh computer. The software presents the user with several windows containing texts, equations, colour-illustrations, drawings and animation. The user can navigate between the windows using buttons.

The maximum strain that the sheet metal can suffer in stretch-forming processes is limited by the phenomena of strain localization and fracture. Both are strictly connected with the stability loss of the workpiece. Different possible modes of instability are discussed in the paper. Also the post-stability stages of the forming process are analyzed.
