Abstract

There is possibility of impact loading on composite tubes while they are being placed or operated. Impact loads can be caused by the objects falls and they are able to make considerable internal damages that decrease residual resistance of layers in composite tubes. In the present study, effective parameters such as tube thickness, impact energy and inner diameter on single-wall tubes behavior under impacting and its consequent damages have been studied numerically, using LS-dyna software. Therefore, composite tubes have been modeled using 3D Solid 164 element and CODAM material model and they have been impact loaded with low velocity. In order to validate the numerical results and modeling, some of the numerical results have been compared with experimental data. An experimental sample of F205 hardener, Epon 828 resin and 400 g/m2 glass fiber was used to make the test sample. There is a reasonable good agreement between experimental and numerical results. Result discussion showed that there are no changes in diagram slope with increase in inner diameter. In other words sample strength and its resistance to impact are increased with growing in inner diameter. Furthermore, mean force level of force-displacement diagram goes up with increase in number of layers in composite sample structure which indicates an increase in sample resistance to impact.
