Modeling of thermoplastics under mechanical long-term loading
Research topics
- Evaluation of creep experiments with unreinforced semicrystalline thermoplastic specimens under constant and cyclic long-term loads
- Development of a phenomenological material model to predict the mechanical long-term behavior of the given thermoplastic for loading and unloading situations
- Prediction of failure of specimens and components
- Development of accelerated computation schemes for cyclic load profiles considering inelastic material models
- Therefore, cost reduction of finite element simulations with large numbers of load cycles
