Abstract: Orthotropic cylindrical shells with discontinuity in the thickness and subjected to axisymmetric loading have been analysed. A higher order finite element based on the thick shell theory is used for the analysis. The material used is a glass/epoxy composite with 0� and 90� fibre orientation with respect to the axial direction of the cylinder. The loadings considered are uniform internal pressure and circular ring load at the mid-section. Numerical results are presented for various end conditions and step-ratios in the thickness. The weight of the shell is kept constant for various step-ratios. It has been shown that 90� fibre orientation gives less deformation and stress for axisymmetric loading than 0� fibre orientation. The variation in the thickness reduces the maximum stresses for some cases of loading and end conditions presented in this paper. ? 1994.
