- Abstract:
- Current research is aimed to create functional material models out of test data to use them in numerical simulations. This process contains several material tests such as tensile tests and dynamic mechanical analyses at different temperatures. All determined test results were used as input data to process model parameters. The selected material models are the hyperelastic Odgen-model, the viscoelastic Prony-series and the hyper-viscoelastic Bergström-Boyce model. After the implementation in ABAQUS/CAE, a comparison of real tensile test data and simulated tensile tests under the same circumstances was developed to ensure the correctness of the models. Finally, a Diabolo specimen was modeled and loaded in the same way as in real-life fatigue tests under tensile loading. This simulation provides information about the stress-strain behavior of the specimen and is meant to build calibration curves which are used for strain-based Wöhler curves later on.
