Regarding the reported capabilities and the simplifications of the smoothed particle hydrodynamics (SPH) method, as a mesh–free technique in numerical simulations of the deformation processes, a 2–D approach on cold rolling process was provided. Using and examining SPH on rolling process not only caused some minor developments on SPH techniques but revealed some physical realities. The chosen test case for rolling is 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, and the results showed good agreements. Moreover, as the final main test, the effect of some affective parameters; roll diameter, percentage of thickness reduction of the strip, and the rolling speed has been studied. In current study not only some developments of using the SPH technique were achieved, but also, could present the capability of the SPH for more simple numerical approaches for such complicated deformation processes
