摘要

这项工作的兴趣是分析孔隙率对幂律功能梯度梁在各种边界条件下的非线性热稳定性响应的影响。根据欧拉-伯努利梁模型进行建模，其中材料特性的分布是模仿多项式函数。假设热负载不仅是均匀的，而且是线性的以及非线性的，并且温度在厚度方向上上升。讨论了孔隙率参数、长细比和幂律指数对P-FG梁热屈曲的影响。

Influence of porosity on thermal buckling behavior of functionally graded beams

The interest of this work is the analysis of the effect of porosity on the nonlinear thermal stability response of power law functionally graded beam with various boundary conditions. The modelling was done according to the Euler-Bernoulli beam model where the distribution of material properties is imitated polynomial function. The thermal loads are assumed to be not only uniform but linear as well non-linear and the temperature rises through the thickness direction. The effects of the porosity parameter, slenderness ratio and power law index on the thermal buckling of P-FG beam are discussed.
