Causes flame like depressions on the sheet surfaces but can be eliminated by temper rolling, but the sheet must be formed within a certain time period after rolling.AnisotropyDetermines thinning behaviour of sheet material during stretching - important in deep drawing operations.Residual StressesCaused by non-uniform deformation during forming, causes part distortion when sectioned and can lead to stress-corrosion cracking - reduced or eliminated by stress relieving.Spring-backCaused by the recovery of the plastically deformed sheet after unloading, will cause loss of dimensional accuracy. Soled by 'over-bending' and other specialised techniques.WrinklingCaused by compressive stresses in the plane of the sheet can be used to increase the stiffness of some parts but can be controlled by proper tool and die design.Generally pressing / forming stretches the material to elongate the grains in the material so that is will follow the form that is required. Obviously if stretched too much it will crack. Another thing that has to be added is that when the sheet material is rolled the grains flow in a certain direction, if the pressing / forming operation requires the material to be stretched against the grain flow of...
