FATIGUE DESIGN SENSITIVITIES OF STATIONARY TYPE 2 HIGH-PRESSURE HYDROGEN VESSELS
John EmeryGrand Ballroom C
Common manufacturing processes for type 2 high-pressure hydrogen storage vessels use a surrogate measure of the desired residual stress, e.g., target strain on the external surface or target internal pressure. The critical value of these measures is chosen to impart residual stress sufficient to achieve a certain fatigue performance for the targeted operational pressure cycling and with given assumptions about the liner and overwrap geometry and materials. This paper uses computational simulation to study the sensitivities of fatigue performance to associated design specifications and assumptions.
