Abstract
The subject of this work is focused on strength analysis of filament-wound composite tubes made of E glass/polyester under internal pressure. The primary attention of this investigation is to develop a reliable computation procedure for stress, displacement and initial failure analysis of layered composite tubes. For that purpose we have combined the finite element method (FEM) with corresponding initial failure criterions. In addition, finite element analyses using commercial code, MSC/NASTRAN, were performed to predict the behavior of filament wound structures. Computation results are compared with experiments. Good agreement between computation and experimental results are obtained.

Summary
The subject of this work is focused on strength analysis of filament-wound composite tubes made of E glass/polyester under internal pressure. Filament-wound, fiber-reinforced polymer-matrix composite laminate tubes have been used for a wide range of new engineering applications, owing to their high specific stiffness, strength and superior corrosion resistance. A systematic study, based on analysis and experiments, has been conducted to investigate the mechanisms and failure mechanics of filament-wound composite laminate tubes under internal pressure [1]. Owing to their anisotropic nature, fiber reinforced composite material properties can be tailored by varying the laminate fiber orientations This is beneficial as the stiffness or strength of a structure can be maximized. The finite element method, based on Mindlin plate and shell theory, is used in this application in conjunction with initial failure criterions in order to obtain the failure load of layered composite tube under internal pressure. The main objective of this work is a comparison of calculation-acquired pressure values, which causes the initial failure of tube models, and experimentally obtained values for hydraulic burst pressure of filament-wound composite tubes, i.e. the verification of computation procedure for initial failure analysis of composite tube
