Influence of the constitutive flow law in FEM simulation of the Radial forging process [PDF]
, 2013 Radial forging is a widely used forming process for manufacturing hollow products in transport industry. As the deformation of the workpiece, during the process, is a consequence of a large number of high-speed strokes, the Johnson-Cook constitutive law (
