Analysis of protective structures made of various composite materials subjected to impact

The analysis considers the problem of the impact energy dissipating elements used to reinforce the existing protective road barrier systems. The results of experimental tests and numerical simulation of a basic energy-absorbing element, in the form of a sleeve made of glass–epoxy composite, are presented. These results were also used for the development of a reliable numerical model of a road barrier and for simulation of the barrier hitting. The obtained results allowed for the practical usability assessment of an example solution.
