analysis of multi layered filament wound composite pipes under internal pressure
Composite Structures, 2001Co-Authors: M Xia, H Takayanagi, K KemmochiAbstract:Abstract Composite pipes in this study are composed of multi-layered filament-wound (FW) structures. Each layer of the pipes is assumed to be anisotropy. Based on the three-dimensional (3-D) anisotropic Elasticity, an exact Elastic Solution for stresses and deformations of the pipes under internal pressure is presented. Moreover, detailed stress and strain distributions for three given angle-ply pipe designs are investigated by using the present theory. The shear extension coupling is also considered because the lay-up angles with + φ and − φ layers cannot exist in the same radius. For cylindrical-pressure vessels with different angle-ply pipe, the ratio of applied hoop-to-axial stress in each layer is different. Even if quite a thin-walled pipe, the ratio of hoop-to-axial stress is no longer a constant of 2:1.

analysis of filament wound fiber reinforced sandwich pipe under combined internal pressure and thermomechanical loading
Composite Structures, 2001Co-Authors: K Kemmochi, H TakayanagiAbstract:This is a presentation based on the classical laminated-plate theory of an Elastic Solution for the thermal stress and strain in a filament-wound fiber-reinforced sandwich pipe subjected to internal pressure and temperature change. The sandwich pipe is created using resin material for the core layer and reinforced materials with an alternate-ply for the skin layers. Considering the complicated material properties of the skin layers reinforced by alternate-ply composites, the thermal stress analysis is based on treating typical sandwich pipes that are three-dimensional, cylindrical, and orthotropic. A computer program was developed to conduct stress and deformation analyses of sandwich pipe with different winding angles. Moreover, an optimum winding angle of the filament-wound fiber-reinforced materials was designed by using a netting approach analysis.

analysis of multi layered filament wound composite pipes under combined internal pressure and thermomechanical loading with thermal variations
Composite Structures, 2009Co-Authors: H Bakaiyan, H Hosseini, E AmeriAbstract:The composite pipes manufactured by filament winding technology have anisotropic behavior owing to different reinforced ply angles. Composite pipes can be exposed to the thermomechanical loading due to hot fluid that flows into them. In this paper, based on the three-dimensional anisotropic Elasticity, an exact Elastic Solution for thermal stresses and deformations of the pipes under internal pressure and a temperature gradient has been studied. Giving heat convection conditions the variation of temperature field within the pipe is obtained by solving the conduction equation at the wall. The influence of temperature field in the governing equations of thermoElasticity has been considered via a constitutive law. The shear extension coupling is also considered because of lay-up angles. Stress, strain and deformation distributions for different angle-ply pipe designs are investigated using the present theory.
