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
