Modelling and simulation of tyre impacts on stiffened composite panels

Kurzfassung

This paper describes recent progress on materials modelling and numerical simulation of fibre reinforced composite shell structures subjected to high velocity impact loads. A Continuum Damage Mechanics (CDM) model for fibre reinforced composites is applied to model both in-ply and delamination failure during loading. This modelling technique is applied to predict the response of C-frame stiffened composite panels subjected to tyre rubber fragment impacts. In this study, two material technologies (thermoset or thermoplastic resins) used for the manufacturing of the stiffened plates are considered. The main conclusion is that the thermoset panel undergoes higher damage compared to the thermoplastic one.
