Assessing the current modelling approach for predicting the crashworthiness of Formula One composite structures

Current methods for designing Formula One (F1) crash structures are mainly based on costly iterative experiments, aimed at minimising the component mass and maximising driver safety. This paper assesses the simplified block approach used in F1 to computationally predict crashworthiness. Quasi-static and dynamic crush experiments of flat and tubular coupons are presented, to generate data for the modelling of a F1 Side Impact Structure (SIS). The crushing efficiency of these coupons is found to be dependent on geometry, ply orientation, and crushing velocity. This modelling strategy yields results which compare favourably with those obtained from the quasi-static and dynamic experimental testing of a full-scale SIS, but also highlight areas which require further work to improve accuracy.
