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, a simple failure criterion as a reference marker was introduced. The distance between the die and blankholder was kept constant. Major results from the study was: For the mild blank material the difference between failure with rigid tools and elastic tools was minor, for the high strength blank material the difference was major. For the medium range blank material an anomaly was observed.
