Simulation of Rolling Billet in Oval Pass by Explicit Dynamics Elastic-Plastic FEM

A study on prediction of deformation behavior (rolling force, equilibrium strain, spread) during rolling was accomplished with FE code ANSYS/LS DYNA. The laboratory experiments were conducted on a two high mill with roll diameter of 170 mm to approve the results of simulation by explicit dynamics FEM. It was found that there is a good agreement between calculated and experimental data, which means that the shape rolling could be analyzed by means of explicit dynamics FEM.
