A hierarchy of models for the design of composite pressure vessels

Abstract

The mechanical response of pressure vessels to an applied internal pressure is essentially controlled by a few key parameters, related both to the overall geometry of the structure and to the orientations and thicknesses of the composite layers. The role of each parameter, and the way they interact to determine the structural response, can be apprehended at a very early design stage by using simple material and structural models, which enable to explore a wide range of designs with minimal computational cost. More complex models can then be called into play to predict the detailed structural response, including crucial information such as the burst pressure and failure mode. This paper discusses a hierarchy of models with increasing levels of details and complexity, which are useful to gain increasing insight on the pressure vessel response all along the design process.

A Review on Industrial Perspectives and Challenges on Material, Manufacturing, Design and Development of Compressed Hydrogen Storage Tanks for the Transportation Sector

“…(2 − ) An important phase of step no. 1 is to find out the preliminary sizes of the composite layup for the hydrogen tank, which can be accomplished using the composite laminate theory (CLT) or the netting analysis [153]. The layup sequence definition and the thickness of each layer are evaluated using CLT.…”

Strength and Failure Analysis of Fiber-Wound Composite Gas Cylinder via Numerical Simulation

“…In terms of fatigue performance, the cycle life of the fiber layer is much longer than that of the metal liner, so the fiberwound composite cylinder has the failure mode of leakage before blasting that the metal cylinder does not have. At present, there are various designs of fiber-wound composite gas cylinders [13][14][15][16][17], which are widely used in rocket missiles [18,19], energy storage and transportation [20][21][22], new energy vehicles [4,[23][24][25][26], industrial production [27][28][29], medical rescue [30,31] and other fields.…”
