Abstract

The main goal of this study is to investigate the forming kinematic and the developed loads during the countersinking process. A compression test was performed to characterise the behaviour of the used sheet metal. An elasto-plastic finite element model was used to predict the forming kinematics, the developed loads and the final shape of the countersink. A configuration with a maintained blank-holder was performed for this study. New phenomena of forming kinematic were observed and investigated. The simulation results were in good agreement with the experiments, and they showed the capability of the adopted finite element model to predict the loads and the final shape of the countersunk workpiece.
