Stress analysis of layered thick-walled composite pipes subjected to bending loading

The current study is focused on stress analysis of multi-layered thick-walled fibre reinforced composite pipes subjected to bending loading. The composite pipes manufactured by filament winding technology of different lay-ups and designs are considered. The research focuses on the pipes with multi layered outer part and thin homogeneous inner layer. It gives comparative analysis of stresses distribution in the pipes with inner homogeneous layer and inner composite layer of 0° fibre orientation. The multi-parametric investigation of stress distribution as a function of the inner layer material properties, its thickness, the number of layers, lay-up and the magnitude of bending load was carried out.
