Beam model for thermal buckling analysis of thin-walled functionally graded open section beams

Paper presents the beam finite element model for thermal buckling analysis of thin-walled functionally graded (FG) open section beams. The model is based on Euler-Bernoulli-Navier bending theory and Vlasov torsional theory. The analysis is performed in a load-deflection manner using the framework of corotational formulation. Material properties are assumed to be graded over the wall thickness. The critical buckling temperature of FG box beams with diferent value of power law index p for different types of boundary conditions, clamped-clamped (CC), clamped- simply supported (CS) and simply supported (SS) are given in order to investigate the effects of the power-law index and skin-core-skin thickness ratios on structural behavior at thermal loading.
