Simulation of Cold Rolling Process Using Smoothed Particle Hydrodynamics (Sph)

A mesh-free 2-d numerical approach was examined for cold rolling process to gain a more simpler and faster way to simulate such complicated case. regarding the wide range of gained reports about the simplicity and computationally efficient characters of the smoothed particle hydrodynamics (sph) method, the computational simulation stands on sph technique in current numerical study. in this paper, the computational efforts not only confirm the advantages of using the sph, but also reveal some improvements in simulation efficiencies. the rolling test was performed for an aluminum strip: al 6061. in this way, the rolls assumed to behave as rigid bodies and, the aluminum strip assumed to behave as an elastic-plastic continuum. in order to achieve the required assurance of the employed technique, the computed stress distribution patterns were compared with those reported from a finite element study. the comparison reveals good agreements of the two computed results. moreover, as the final test case, the effect of some parameters that have been reported to play the main role in case; roll diameter, percentage of thickness reduction of the strip, and the rolling speed has been studied. regarding all parts of the current work, it may be concluded that the sph can be sufficient tool to gain a rapid and simple simulation for such complicated cases.
