The stress-state is said to be plane when the direction normal to the plane is a principal stress direction and the magnitude of the stress in this direction is zero. This situation occurs when a sheet is loaded along its edges in the plane of the sheet.

Ultrasonic imaging of sheet metal forming
Ultrasonics, 2004With sheet metal hydroforming, a sheet metal is formed by a liquid medium under high pressure (up to 1000 bar) and a cavity contour (die). As the exact state of forming is of interest, an ultrasonic imaging system is under development. The task is to determine the geometry of a sheet metal contour with respect to the original (before forming) and the ...

A novel sheet metal forming method—Millipede forming
Journal of Materials Processing Technology, 2011Millipede forming, a novel sheet metal forming method, has been proposed and developed recently to overcome fundamental limitations in conventional roll forming. For this new method, there are two main aspects: use of an optimal transitional surface and implementation of a method to feed the strip through the transition surface.

A Review on Electromagnetic Sheet Metal Forming of Continuum Sheet Metals
SAE International Journal of Materials and Manufacturing, 2019<div>Electromagnetic forming (EMF) is a high-speed impulse forming process developed during the 1950s and 1960s to acquire shapes from sheet metal that could not be obtained using conventional forming techniques. In order to attain required deformation, EMF process applies high Lorentz force for a very short duration of time.

For the purpose of this chapter, sheet metal forming is briefly defined as the forming of sheet, strip or plate by methods which are not intended to alter the thickness of the metal at any point. The definition eliminates what is usually understood by operations such as hot and cold forming, forging or embossing, etc.These are dealt with elsewhere in ...

International Materials Reviews, 1981
Sheet-metal forming is gradually changing from a craft-based to an engineering-based process. The review acknowledges the metallurgical improvements that have been made in sheet metals and in tool steels, and concentrates on research aimed at understanding and describing the mechanical properties of sheet metals in a more quantitative manner.

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.
