Various tests can be carried out to characterise different materials regarding their forming and damage behaviour. Based on results from compression or tensile tests flow curves are calculated to describe the plastic forming behaviour. In order to take into account the respective process requirements, the characterization tests can be carried out in a wide temperature and strain rate range. Furthermore, bulge tests, which can be combined with an optical measurement system, can be performed in order to determine forming behaviour of sheet metal materials at high plastic strains. Moreover, forming limit curves (FLC) can be recorded and evaluated to describe damage behaviour of sheet metal material. A developed experimental setup allows isothermal performance even at high temperatures up to 1050 °C. Another focus is the experimental parameterization of stress-based damage models. The use of optical metrology and DIC enables the generation of additional information and validation data for numerical simulation. Also, the phase transformation behaviour of various materials under different time-temperature profiles is determined and time-temperature transformation diagrams (TTT) and time-temperature austenitisation diagrams (TTA). calculated accordingly.
