OpenForm - Integrierter Pre- und Postprocessor für industrielle Tiefziehsimulation

Since the mid nineties sheet metal forming simulation has been widely used to take the uncertainty out of the die design process. When forming simulation was first introduced into the work of die designers the main focus was on the prediction of thinning, cracking and draw-in of the sheet metal. Later, the prediction of wrinkling, springback and surface defects became challenges finite element forming simulation packages had to cope with. While the prediction of thinning, cracking and material draw-in has now become a relatively easy task for numerical simulation, springback prediction and the detection of surface defects are still great challenges requiring advanced finite element simulation software and considerable expertise and experience in its application. More recently, hot forming simulation has added to the complexity of numerical simulation in the field of sheet metal forming. Since thermodynamical effects also have to be considered in the simulation of hot forming processes, even more experienced users are necessary to ensure that reasonable results are achieved.
