Modelling the test methods used to determine material compatibility for hydrogen pressure vessel service
CP Looney, ZM Hagan, MJ Connolly… - International journal of …, 2020 - Elsevier
This work aims to create finite element models to simulate the three ISO 11114-4 test
methods applicable to hydrogen gas cylinders, coupled with calibrated constitutive models,
to predict the deformation response of each. Experimental measurements are used to
calibrate a monotonic constitutive model and a constitutive model of cyclic deformation. Six
finite element solid models are discussed: monotonic tensile test of dog bone-shaped
specimens, strain-controlled fatigue test of dog bone-shaped specimens, ISO test Method A …
