Abstract
An experimental test series was carried out to determine input parameters for a well-known continuum damage mechanics elementary ply plasticity model. A full suite of data was obtained for a carbon fibre and an S2-glass fibre-reinforced composite material, both currently used in the aerospace industry. Models were implemented using the experimentally determined input parameters and predictions for in-plane behaviour found good agreement with experiments for both material systems. In addition, model predictions for cyclic loading accurately captured reload moduli and plastic strain magnitude.
