WebbTo understand the forming (by deformation process) of metal, it is important to know the structure of metals. Metals are crystalline in nature and consist of irregularly shaped grains of various sizes. Each grain is … WebbMetal forming processes, also known as mechanical working processes, are primary shaping processes in which a mass of metal or alloy is subjected to mechanical forces. …

WebbThe present study is devoted to extending Barlat’s famous yield criteria to tension–compression asymmetry by a novel method originally introduced by Khan, which can decouple the anisotropy and tension–compression asymmetry characteristics. First, Barlat (1987) isotropic yield criterion, which leads to a good approximation of yield loci … 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 … port of galveston camera
