a probabilistic damage behavior law for Composite material dedicated to Composite Pressure Vessel
International Journal of Hydrogen Energy, 2015Co-Authors: Stephane Villalonga, F Nony, H GalianoAbstract:Abstract This paper written in the framework of OSIRHYS IV project which aim is to clarify uncertainties and approximations of high Pressure Vessel Composite design and calculation. The project, headed by CEA, mainly consists in the comparison between experimental results on type IV hydrogen high Pressure storage Vessel and numerical results. This paper presents a Composite damage behavior law whose specificity is to take into account the variability of some material parameters. A model of wound notched structures is realized and compared with experimental results in order to verify the capability of this law to model the behavior of the Composite used in OSIRHYS IV type IV hydrogen storage Vessel.

a progressive failure analysis of a 700 bar type iv hydrogen Composite Pressure Vessel
International Journal of Hydrogen Energy, 2015Co-Authors: David Leh, Philippe Saffre, Pascal Francescato, Robe Arrieu, Stephane VillalongaAbstract:Abstract 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.

3d full field deformation monitoring of fiber Composite Pressure Vessel using 3d digital speckle correlation method
Polymer Testing, 2006Co-Authors: L Meng, Xuefeng Yao, H Y YehAbstract:The 3D full-field deformation of a carbon fiber/epoxy Composite Pressure Vessel are studied using a 3D digital speckle correlation method. The basic principles of 3D digital speckle correlation method are briefly introduced. The 3D full field displacement and strain distribution of the Composite Pressure Vessel were evaluated under internal Pressure loading. The average strain value shows good agreement with the results obtained from conventional electrical-resistance strain gauge technology. The results reveal that the 3D digital speckle correlation method is suitable for deformation measurement of Composite Pressure Vessels in real engineering practice.

full field deformation measurement of fiber Composite Pressure Vessel using digital speckle correlation method
Polymer Testing, 2005Co-Authors: L B MengAbstract:Applications of the digital speckle correlation method (DSCM) for the full-field deformation measurement of carbon fiber/epoxy Composite Pressure Vessel were investigated and the basic principles of displacement measurement by the DSCM are briefly given. The full-field displacement and strain distribution of a Composite Pressure Vessel were evaluated under internal Pressure. The results of the average strain value show a good agreement with the results from conventional electronic strain gauge technology. The results reveal that the DSCM is suitable for deformation measurement of Composite Pressure Vessels in real engineering practice.

experimental method and numerical simulation demonstrate non linear axial behaviour in Composite filament wound Pressure Vessel due to thermal expansion effect
International Journal of Hydrogen Energy, 2015Co-Authors: Pongsak Nimdum, Aramee Patamaprohm, Jacques Renard, S VillalongaAbstract:Abstract The aim of this study is to understand the non-linear axial behaviour at the beginning of pressurisation in Composite Pressure Vessel made by filament winding technique. X-ray method was used in order to investigate the presence of gap around dome area. This gap induced by debonding between Composite shell and metallic boss during cooling stage of curing process due to different thermal expansion of Pressure Vessel components. Then, gap effect on mechanical behaviour was investigated by digital image correlation (DIC) and 3D finite element method (3D-FEM). We found that this effect induces local bending on dome area and induce a nonlinear behaviour response in axial direction at the beginning of internal Pressure loading. In addition, a degree of nonlinearity depends on debonding length. Acoustic emission (AE) activity confirm this assumption since typical recording of AE signal represented a high duration, rise time and absolute energy but low frequency content which is correspond to the friction of contact surfaces.
