The knowledge of the mechanical behavior and metallic materials when subjected to unconventional situations which involve shear rates is still largely unexplored in the literature in general. One reason for this lack of knowledge is, in fact, the difficulty of implementation and standardization of mechanical experiments with machines that are able to monitor and supervise their implementation throughout the trial, to obtain reliable properties and subsidies providing material correct modeling. This paper presents a method for applying a simplified and consistent mathematical model, based on the fundamental mechanical properties obtained in the Johnson-Cook tensile test. The modeling procedure is validated in experiments deformation traction control rates compared with traditional Johnson-Cook equation. The modeling procedure is valid from randomized controlled traction in SAE 1020 steel.
