1. High-speed forming of metallic materials

1.1 Various high-speed forming modes

Most metal objects have undergone one or more shaping operations prior to use. This shaping takes place through plastic deformation of the metal in its solid state. Remember that the plasticity of a material corresponds to its ability to exhibit permanent deformation leaving its volume invariant after application of a stress state verifying the plasticity criterion, the critical value of which is defined by the flow stress σ 0 . Metal forming can be carried out with or without...
