Nonlinear behavior analysis of filament — wound composite tubes
Sun J., Růžička M., Uher O.
pages 316 - +9p., full text

Our recent experiments on filament-wound composite tube showed that unidirectional and cross filament-wound composite tubes had non-linear behaviour even under axial loading. This non-linear behaviour, in our opinion, is mainly caused by non-linear shear behaviour. In this paper, the non-linear constitutive relation developed by Hahn and Tsai is adopted in our analysis where a piecewise linear approximation is used for unidirectional filament wound tubes. The non-linear numerical and experimental results of unidirectional filament wound tubes have a good agreement. Also in these paper, some experimental results and analysis about cross filament wound tubes are given.
