Effects of shear loading on stress distributions at sections in thick composite tubes

In the previous study (Yazdani Sarvestani, submitted for publication), a new simple-input displacement-based method (based on layerwise formulation) was developed for the stress analysis of thick laminated composite straight tubes subjected to cantilever loading. This method provides a quick, convenient and accurate method for the determination of 3D stresses in thick composite tubes subjected to both bending and shear loading. The technique in this method is now used to study the behavior of stress distributions in thick composite straight tubes with different lay-up sequences considering effects of the shear load part of cantilever loading. Knowledge is extracted from the parametric study showing effects of the orientations of different layers on the stresses.
