Nonlinear Bending Analysis of Cylindrical Panel under Thermal Load

Abstract

In this communication, the nonlinear bending behaviour of laminated cylindrical panels in the presence of thermal load has been studied using the finite element-based simulation package ANSYS. The efficacy of present numerical results is compared with published results. Thereafter, the effect of radius-tospan ratio (R/a) on the nonlinear static response of isotropic and laminated panels under thermal load is studied here. Moreover, the nonlinear bending deflection verses x-axis of cylindrical panels at different thermal loads is presented here that will serve as benchmark for future research.

“…When homogeneous heat stress is applied to curved (trapezoidal, cylindrical) panels composed of laminated composites, Kumari and Lal investigate the flexural characteristics of these panels. These panels are often seen in military vehicles, cars, ships, and aeroplanes 151,152 . The thermal characteristics of the eucalyptus fiber composite, which is based on polyester and has volume fractions of 30%, 40%, and 50%, indicate that the thermic stability drops significantly as the amount of fiber included in the composite increases, as compared to the pure polyester material.…”
