Modelling and Crash Simulation of Long-Fibre-Reinforced Thermoplastics

The presentation deals with the development, calibration and verification of a constitutive model for the deformation and failure of long-fibre-reinforced thermoplastics (LFT). The model has been implemented as a user-defined material model into LS-DYNA and is employed for the simulation of a component subjected to crash-loading. Numerical results are compared with respective experiments. Furthermore, a methodology to incorporate in crash simulations the spatial distribution of fibre orientation in the component determined from preceding simulations of the manufacturing process is discussed.
