Year: 2013
Type: article
Abstract: In this investigation, the mechanical behavior of sandwich hollow cylinders under internal pressure is carried out numerically. Functionally Graded (FG) foam core sandwich hollow cylinders are fabricated by employing filament winding technique with [±55] carbon fiber/epoxy as skins with the FG foam core made using centrifugal casting technique of polyurethane foam with epoxy resin. A finite element (FE) model is developed employing a FE commercial code to determine the stresses and deformations. Numerical analysis is performed to find the effect of one particular functional grading on the deformation and stresses. The results are compared with similar tubes using uniform PU foam core. The results show that grading the foam core affects the displacements and stresses in a significant way. The FG foam sandwich core tube possesses a lower displacement magnitude and higher maximum stresses taking into account the mass of the two types of pipes and rigidity compared to uniform PU foam core under internal pressure of 10 MPa.
