| Abstract: | Hydrogen storage cylinders are key element in expanding hydrogen energy-based technologies to various stationary (telecom towers, power systems at various remote location) and mobile (vehicular) applications. Type III hydrogen cylinders are the promising candidate due to their large volumetric storage capacity at high pressure. They have thin liner as core made of Aluminium alloy, to control the hydrogen permeability and to provide strength, that is wrapped with thick carbon fibre reinforced plastic composite to provide majority of the strength required to hold high pressure gaseous hydrogen (of the order of 350 bar or more). Type III cylinders are advantageous due to their corrosion resistance, light weight and operational efficiencies. For operational safety and estimating the service life of these cylinders (filling and refilling cycles), it is important to understand the fatigue behaviour of a cylinder material under high pressure hydrogen conditions. To this end, a simulation framework for modelling the fatigue crack growth behaviour in Type III composite cylinder material under high pressure hydrogen is developed within 2-D finite element framework enhanced with fracture mechanics concepts to predict service life of cylinder. The framework is developed within Abaqus finite element program coupled with python scripting using quarter point method to obtain the stresses at the crack tip that govern crack growth behaviour. The stress intensity factor (SIF) and energy release rate value plays the role of important fracture mechanics parameters which is used in simulation to get fatigue crack propagation direction. In this work, focus is on the LEFM theory that is used for crack growth study in Aluminium liner. Analysis is performed in small steps, where in the first step stress intensity factor, crack propagation direction is calculated for an initially cracked liner of composite cylinder. In further small steps, the stress intensity factor (SIF) and crack propagation direction is calculated for the propagating crack while taking care of the liner-wrapping interface strength and stacking sequence of the composite wrapping. It is found that the stacking sequence plays a vital role in achieving improved service life of Type III cylinder. |
