This is one of the fundamentals of glassblowing, referring to shaping heated glass with mechanical force. With respect to bead making, very little force can be tolerated, but gravity certainly is used to influence the shape of a bead. There are several techniques used to manipulate glass that are forms of bending, such as raking.
A process used to produce bent glass in which a plate of glass is placed in a horizontal mould and then slowly heated at approximately 600°C, at which the glass softens sufficiently and takes the shape of the mould. The glass is then slowly cooled to avoid any internal stress.
Changing the shape of metal sheet using successive pairs of forming rollers. Bending does not change the thickness of the metal except at the bend radius where a slight thinning occurs. Generally applied to forming it is the creation of a formed feature by angular displacement of a sheet metal workpiece.
the property of being bent or deflected
The bending of aluminium can be performed both as the edge bending of sheets and as the bending of profiles over a bending jig. Generally, aluminium requires greater care when bending compared to steel, for example. Essentially, the bending radius must therefore be larger. Fracture elongation Fracture elongation specifies the percentage elongation for a specific measuring range of a test piece after loading to fracture by tensile testing.
Generally applied to forming. Creation of a formed feature by angular displacement of a sheet metal workpiece. See also "Drawing" and "Forming."
A term typically applied to a metal forming process. It is the creation of a formed feature by angular displacement of a sheet metal workpiece. The straining of material, usually flat sheet or strip metal, by moving it around a straight axis lying in the neutral plane. Metal flow takes place within the plastic range of the metal, so that the bent part retains a permanent set after removal of the applied stress. The cross section of the bend inward from the neutral plane is in compression; the rest of the bend is in tension. See bending stress, forming, and drawing.
