摘要

采用新的修正幂律公式，给出了FG夹芯板在轴向和双轴载荷作用下临界屈曲的一种新的简单解。本研究同时考虑了孔隙度的均匀分布和不均匀分布。假定夹层板表面的材料性能在厚度方向上按照修正的幂律分布按组分的体积分数进行分级。利用高阶剪切变形板理论，推导了不同边界条件下FG夹芯板的平衡方程和稳定性方程。结果表明:孔隙率的分布形状、梯度指数、加载类型和功能梯度层厚度对功能梯度夹层板的屈曲响应有显著影响;

Analysis on the buckling of imperfect functionally graded sandwich plates using new modified power-law formulations

A new simple solution for critical buckling of FG sandwich plates under axial and biaxial loads is presented using new modified power-law formulations. Both even and uneven distributions of porosity are taken into account in this study. Material properties of the sandwich plate faces are assumed to be graded in the thickness direction according to a modified power-law distribution in terms of the volume fractions of the constituents. Equilibrium and stability equations of FG sandwich plate with various boundary conditions are derived using the higher-order shear deformation plate theory. The results reveal that the distribution shape of the porosity, the gradient index, loading type and functionally graded layers thickness have significant influence on the buckling response of functionally graded sandwich plates.
