Abstract [en]
Dies in sheet metal forming simulation are commonly modeled as rigid, although they are elastic. The influence of elastic response in the dies can be split into two types, global and local deformation. Local deformation occurs where large pressure in the tool prevails typically in the die radii. A numerical study on local elastic tool deformation was performed. Three different blank materials and three tool materials were used. The geometry was from the FTF 2015 conference, triangle die. The blank was modeled with the same material model, and a simple failure criterion as a reference marker was introduced. An important result from the study was: The draw depth difference for the chosen evaluating condition between rigid tools and elastic tools was in the region 5–12.5% deeper using elastic tools.
