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. Fiber reinforced composites are increasingly being introduced into a variety of structures in aeronautical, mechanical and marine engineering applications where high ratios of stiffness and strength to weight are of paramount importance. Filament-wound, fiber-reinforced polymer-matrix composite laminate tubes hav
