George, N.Jeyaraj, P.2026-02-052018International Journal of Structural Stability and Dynamics, 2018, 18, 12, pp. -2194554https://doi.org/10.1142/S0219455418501535https://idr.nitk.ac.in/handle/123456789/24913The influence of nonuniform heating on the critical buckling temperature of laminated glass-epoxy composite beam has been investigated experimentally with the help of a novel experimental setup. The beam is numerically investigated using nonlinear finite element analysis. An initial geometric imperfection is introduced to the modeled geometry in numerical technique to have an experimental-numerical comparison of temperature-deflection plot. The results indicate that the critical buckling temperature of a uniformly heated beam has a significant difference in comparison to the nonuniformly heated beam and it depends on the heating source location and the resulting temperature distribution along the length direction of the beam. © 2018 World Scientific Publishing Company.Composite beams and girdersLaminatingComposite beamExperimental investigationsInitial geometric imperfectionLaminated composite beamNon-linear finite-element analysisNonuniform heatingNumerical techniquesThermal bucklingLaminated composites
