摘要

本文采用三次剪切变形理论对功能梯度多孔板的弯曲响应进行了研究。fg板的性能按幂律分布变化，考虑到孔隙率的影响，幂律分布被修正为近似材料特性。利用虚功原理推导了平衡方程，并用纳维耶法求解。讨论了各种数值结果，以证明功率指数、孔隙率参数和几何比的变化对FG多孔板弯曲响应的影响。

Bending analysis of functionally graded porous platesvia a refined shear deformation theory

In this investigation, study of the bending response of functionally graded (FG) porous plates is presented using a cubic shear deformation theory. The properties of the FG-plate vary according to a power-law distribution which is modified to approximate material characteristics for considering the effect of porosities. The equilibrium equations are derived by using the principle of virtual work and solved by using Navier\'s procedure. Various numerical results are discussed to demonstrate the influence of the variation of the power index, the porosity parameter and the geometric ratios on the bending response of FG porous plates.
