Theory of metal forming
In metalworking, forming is the fashioning of metal parts and objects through mechanical deformation; the workpiece is reshaped without adding or removing material, and its mass remains unchanged. Forming operates on the materials science principle of plastic deformation, where the physical shape of a material is permanently deformed.

Webb10 mars 2024 · Different from the cross-section profile defects caused by uneven roll wear or external forces during hot finishing rolling, the edge warping defect often occurs and has special local characteristics. However, the cause and control method of edge warping are still unclear. By superposition calculating the roll shape, it is found that the high-order … WebbFundamentals of Metal Forming: Theory of Plasticity – stress tensor – Invariants of stress strain – hydrostatic & deviator components of stress – flow curve – true stress and true strain. Yielding criteria – yield locus – octahedral shear stress and shear strains. Plastic deformations of crystals – critical resolved shear stress.
Webb5 juni 2012 · The theoretical models established for this purpose showed that the forming load depended on such factors as die geometry and friction, for instance, and in hot forming also on the forming speed. With the development of theoretical methods, it also became possible to calculate the effect of each factor on the forming load.

Webb2) For most ductile metals that are isotropic, the following assumptions are invoked since they have been observed in many instances: 1. There is no Bauschinger effect, thus the yield strengths in tension and compression are equivalent. 2. Constancy of volume prevails so the plastic equivalent of Poisson’s ratio is 0. 5. 3. simple white icing for cinnamon rollsWebbMetal forming is a general term for a large group, that includes a wide variety of manufacturing processes.
