Numerical simulation of the roll levelling of dp1000 steel using a nonlinear combined hardening material model [PDF]
Computer Methods in Materials Science, 2014 The roll levelling is a forming process used to remove the residual stresses and imperfections of metal strips by means of plastic deformations. During the process the metal sheet is subjected to cyclic tension-compression deformations leading to a flat ...
