In this work, the use of texture manufacturing technology (Geometric shapes) to the assembly areas of Aluminum / Aluminum plates is explored. In order to improve the shear strength values of the single joint adhesive layer, it is necessary to model structural reinforcements at the interface of the bonded assembly. Through the Abaqus software; models will be developed to simulate the stress distribution along the region of interaction between the plates and the single joint adhesive layer. by an economic choice. The analysis of the dimensions of the lap length and the thickness of the adhesives are the main parameters to be modified to optimize the geometry of the assembly, because an increase in the resistance of the joint is accompanied.

Three kind of polymer are used in the present analysis: High density Polyethylene HDPE, Light low density Polyethylene LLDPE and finally blend of LLDPE/HDPE. The effect of the mechanical properties on the behavior of type IV vessel may be then investigated. In the present paper, the effect of the order of the circumferential winding on the stacking sequence may be then investigated. Based on mechanical considerations, the present model provides an exact solution for stresses and deformations on the cylindrical section of the vessel under thermo-mechanical static loading. The result show a good behavior of HDPE liner compared to the other plastic materials. The presence of circumferential winding angle in the stacking improves the rigidity of vessel by improving the burst pressure. Keywords—CNG; Cylindrical vessel; Filament...

For the uid part of the problem, we use the nite volume method, whereas for the part concerning structure, we use the nite element method. Mots clefs : Interaction uide-structure; pale éolienne; simulation; OpenFoam-1.5-dev.
