Isotropic Plasticityons stem from a degree of ignorance about real behaviour, but most often they are necessary if process and design modelling is to be achieved within the limits of present computer technology. The commonest explicit approximation made is that of isotropy. In an isotropic model, the properties of a ma

Numerical Modelling of Forgingniques. The hand forging craft did not become a major industrial process until the development of Nasmyth’s steam hammer in 1840 allowed the production of heavy hot forgings on a regular basis. Since this date, advances in forging equipment have improved the efficiency and industrial viability of th

Rolling Process Modellingy a fixed distance. During forming, a schematic diagram of which is shown in Fig. 11.1, the metal elongates but does not spread in significant measure. The process may be performed at room temperature on a cold mill or at high temperature on a hot strip mill, both of which may consist of one or more
