Abstract

In this research the effects of various parameters on design of composite peressure vessels are studied. For this purpose a composite pressure vessel is designed based on netting analysis approach. Then by using parameters obtained trom the analysis, a simplified model of the capsule is made by a finite element technique. In the next step, by optimizing the simplified model, effective parameters such as variable thickness of the composite shell, variation of the fiber angle in the cap area, and existence of flanges and metallic liner are studied in detail. The results obtainedf all three techniques (netting, simplified and modified models) are compared with each other.Using the modified model, yield pressure for the composite pressure vessel is calculated and the elasto-plastic behavior of metallic liner and propagation of plasticity in this component are studied. The composite material is assumed to be linear-elastic and the liner is considered as an elasto-plastic material. The stress and displacement fields obtained from the modified and netting models are compared. It is shown that netting analysis is not able to design an optimum pressure vessel.Finally, using a failure analysis approach, the first ply failure of the composite pressure vessel is analyzed for all three models. The results show that the magnitude of first ply failure pressure for the netting and simplified models is lower than that of the modified model. To design an optimum composite pressure vessel, all effective parameters studied in this research should be considered in design process.
