Stamping of aluminum alloy is becoming of great interest by the automotive industry in the last years. With the increase in the use of these materials, problems such as die wear, galling and springback, for example, are becoming critical. Among them, the instability of the process to manufacturing-process-windows (holding force pressure windows and drawing speed windows for example) are involving a lot of engineering challenges. As an example, the impact of the use of hydraulic presses against the use of mechanical presses leads to an apparition or solving of fracture problems. Being the drawing speed the main difference between them, numerous effects can be responsible for those differences, e.g. strain rate sensitivity of the plastic behavior, drawing speed sensitivity of the tribological behavior, temperature effect. In that regard, in this work, the strain rate sensitivity of the damage-fracture behavior of the AA5754 material is studied.
