Use of FE Simulation and Servo Press Capabilities in Forming of AHSS and Aluminum Alloys

Production of light weight and crash resistant vehicles require extensive use of AHSS (DP,TRIP,TWIP) and Al alloys to form complex shapes. This paper discusses practical determination of material properties and selection of lubricants for forming AHSS using a die set, designed for deep drawing. Tests were conducted in a 300 ton servo press. Thinning at the critical area of the formed part were measured and compared with FE simulation. Prediction of temperatures in deep drawing of selected DP steels and Al alloys in servo press is also discussed.
