Sažetak
In this paper, thermal buckling analysis of closed thin-walled functionally graded (FG) beams based on Euler-Bernoulli- Vlasov theory is presented. The geometric numerical algorithm is developed using a 1D numerical model based on the application of the spatial finite element beam and UL (updated Lagrangian) incremental formulation. The cross-sectional displacement field includes the effects of warping torsion and large rotations. Material properties are assumed to vary continuously through the wall thickness based on power-law distribution. Three cases of the temperature distribution across the thickness of the cross-section walls are considered, which are uniform, linear and nonlinear. Numerical results are obtained for different closed thin-walled sections for various configurations such as boundary conditions, geometry, skin-core-skin ratios, and power-law index to investigate critical buckling temperatures and post-buckling responses. The accuracy and reliability of the beam model are verified by comparing it with previous research results and several benchmark examples.
