New Specimen Design for Wear Investigations in Dry Sheet Metal Forming

In this study a new specimen for wear investigations on a wear testing stand in dry sheet metal forming will be presented. The study is focused on the investigation of the surface pressure in the contact area between wear specimen and sheet metal (DP600 Z). In a first step a numerical model was developed. The FEM model shows the resulting surface pressure on the specimenâ s surface over the entire length of a 60 mm cycle of wear tests. In the experimental wear investigations conducted on a wear testing stand the high strength steel DP600 with a galvanised surface was used. Both, the numerical model and the experimental validation of the model were carried out at room temperature.
