A horizontal orthotropic multi-layered cylindrical vessel subjected to fluid loading is analyzed by finite element displacement method. The end conditions considered are simply supported-simply supported (SS), clamped-clamped (CC), clamped-free (CF). In the case of varying thickness shell the thickness is varied piecewise linearly. Numerical results are presented for various cases in the form of graphs and tables. © 1991.

Deformation of varying thickness composite cylindrical shell subjected to fluid loading with various end conditions

Computers and Structures

Orthotropic cylindrical shells with discontinuity in thickness and subjected to asymmetric loading have been analyzed. A higher-order finite element based on thick shell theory is used for the analysis. The material used is a glass/epoxy composite with 0 ° and 90 ° fiber orientation with respect to the axial direction of the cylinder. The loadings considered are a line load along the length of the cylinder and a point 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 a 90 ° fiber orientation gives smaller deformations and stresses for asymmetric loading than a 0 ° fiber orientation. The variation in the thickness reduces the maximum stresses up to a certain step-ratio for various end conditions presented in this paper. © 1994.

Deformation of orthotropic cylindrical shells with discontinuity in thickness subjected to asymmetric loading

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.

Deformation of orthotropic cylindrical shells with discontinuity in thickness subjected to axisymmetric loading

The effects of discontinuity in thickness on the stresses and deformations of cylindrical shells under axisymmetric loading have been analysed. Love's first approximation thin-shell theory is used to solve the problem. The loadings considered are uniform internal pressure and circular ring load at the mid-section. The effects of these loads for various end conditions and step ratios in the thickness have been analysed, and the results are presented in the form of tables and graphs. The weight of the shell is kept constant for various step ratios. © 1993.
