This study examines burst simulations of hydrogen pressure vessels manufactured by filament winding. Consideration of composite damage in an optimization process may be helpful in developing cost-effective hydrogen energy carriers and allowing greater use of hydrogen technology for transport and thus satisfy current environmental requirements. In the framework of the OSIRHYS IV project, a comparison of the bursting results of two FE models is presented and discussed. Finally, prospective work is presented.
