Abstract
The mechanical forming in sheet metals is a process fabrication that produces parts for several industrial sectors. Among which can be mentioned the sectors of home appliances and automobiles. In these areas of the industry that are competitive, there is a concern with the reduction of times and costs. In some sectors of the industry, which require bigger resistance, special steels are currently used. The need to use steels with higher resistance limits and the need for lighter products, led to new steels being studied in recent decades. The result of research into new steels, starting in the 1960s, was the significant increase in the use of advanced high-strength steels, driven mainly by the automobile industry. The use of these steels allows working with thinner sheets, however the appearance of failure in this material can be frequent due to the decrease in thickness. Numerical simulation, using computational codes, which describe failure control in ductile materials, is widely used to optimize mechanical forming processes in sheet metal. Therefore, the analysis of sheet thickness as a conformability characteristic in Advanced High Strength Steels and the study of the influence of forming speed on the appearance of failure, is the purpose of this work. Thus, there is necessity to study the mechanism of formation and execution of ductile fracture in metallic materials. The numerical simulation of mathematical models that describe the failure mechanisms in ductile materials is common practice to investigate which failure criteria, in the literature, best represents the results obtained in experimental practice. This study presents computational data collection through literature review, use of computational simulation results with an existing and tested model, obtaining simulation results for formulating conclusions based on the thickness of the forming sheets. The result of this study is a methodology that evaluates the most appropriate speed for forming in DP 600 steel by measuring the deformation in the direction of sheet thickness.
