Increasing costs for fuel and an increasing ecological awareness of the companies have lead to a higher importance of lightweight constructions in the automotive industry. A possibility to make components more energy-efficient is to use aluminum/CFRP (carbon-fiber-reinforced plastics) hybrid structures. In today s state of technology the design of reliable and safe hybrid joints is a big challenge that can be solved using simulation programs in the early embodiment design stage. This paper shows the development of a new method to simulate and estimate the behavior of hybrid aluminum/CFRP hybrid joints in an effective and realistic way. In a first step the joints are explored in an experimental characterization. In a second step, detailed simulation models are created and uncertain parameters are adapted to the experiments using parameter identification methods. After that, the simulation models are used to create meta-models containing the behavior of the joints which in a last step are implemented in simplified abstraction models. This enables product developers to predict the realistic behavior of hybrid structures much faster than before.
