case study pipe bend subjected to combined loads: A comparative finite element analysis and experimental Flexural behaviour of a polyvinyl chloride-lined glass-reinforced plastic composite multi-mitred Published by: http://www.sagepublications.com On behalf of: Institution of Mechanical Engineers can be found at: The Journal of Strain Analysis for Engineering Design Additional services and information for Abstract:The exural behaviour of a glass-reinforced plastic (GR P) multi-mitred pipe bend (MM PB) subjected to combined in-plane bending and internal pressure is presented in this paper. After construction of a polyvinyl chloride (PVC)-lined G R P M MPB, its behaviour subjected to in-plane bending, internal pressure and combined internal pressure and in-plane bending was studied. Smalland large-displacement laminated shell nite element analysis (F EA) results using ABAQU S F E were compared with experiments on an identical specimen. When modelling an M MPB subject to individually applied pressure and bending loads, comparisons exhibited good agreement between linear small-displacement F EA with experimental data. Only large-displacement F EA agreed with experiments when modelling M M PBs subject to combined pressure and bending loads. Largedisplacement F EA showed geometrically non-linear behaviour closely matching the experimental trends.

Finite Element Analysis of the thermo-Mechanical Behavior of composite Pipe Elbows under Bending and Pressure loading

“…Al. [9] which ends with a good agreement between the experimental and the finite element analysis on a composite tubular structure subjected to a combined loading. The elbow in its geometric configuration will cause a variation of stress along its intrados and the extrados from where the analytical solutions that are possible to be implemented [10].…”

An overview of burst, buckling, durability and corrosion analysis of lightweight FRP composite pipes and their applicability

“…The component was tested as a three-dimensional model using 8-node element, where pressure was given as an input to study the shear and peel stresses. Kochekseraii et al [234] analysed the glass fibre reinforced with polyvinyl chloride pipe flexural behaviour, using the ABAQUS FE programme. The pipe was considered as the isoperimetric shell element and subjected to bending in the plane as well as internal pressure.…”

A review of literature for the structural assessment of mitred bends

“…Babaii Kocheckseraii and Robinson [94] using both experiment and finite element analysis, examined the combined effects of pressure and IPB for a poly-vinyl chloride (PVC)-lined GRP multi-mitre. The authors concluded that only large-displacement finite element analysis is suitable for the practical design of bends subjected to combined internal pressure and IPB.…”

“…Ingenhousz [66], Hose [84], Kitching and Hose [85], Babaii Kochekseraii [83] and Babaii Kochekseraii and Robinson [94] conducted experiments on PVC-lined GRP multi-mitred bends. However, in all cases, the GRP lay-up was assumed to be quasi-isotropic.…”
