Abstract: This paper describes the identification of hardening parameters of DCO5 sheet metal and contact friction coefficients using a multi-layered upsetting test (MLUT), the modified two specimen method (MTSM) and a finite element based inverse method The MTSM is adopted in order to identify the friction coefficient between the tools and the stacked circular specimens which are cut from the base material by spark erosion Next, the hardening behaviour is identified inversely by combining the results of a MLUT and finite element simulations of the test setup Finally, the results are compared with standard tensile tests and it is shown that the MLUT is a viable alternative for the identification of the local hardening behaviour of sheet metal where standard test specimens cannot be prepared due to size limitations of the specimen (C) 2010 Elsevier B V All rights reserved
