摘要

本文采用简单迭代法分析了功能梯度材料(FGM)在内外压作用下的变厚度圆盘。FGM圆盘的厚度和材料的杨氏模量沿径向呈指数变化。泊松比被认为是材料的不变量。在平面应力条件下，用Navier方程将问题以微分方程形式表示。位移、应力和应变是在材料级配和变厚度的影响下得到的。考虑了三种不同的材料组合用于FGM盘。将不同功能梯度材料组合得到的圆盘的力学响应与均匀圆盘的力学响应进行了比较，并将结果绘制成图形

Stress Analysis of Functionally Graded Disk with Exponentially Varying Thickness using Iterative Method

In this paper, variable thickness disk made up of functionally graded material (FGM) under internal and external pressure is analyzed using a simple iteration technique. Thickness of FGM disk and the material property, namely, Young’s modulus are varying exponentially in radial direction. Poisson’s ratio is considered invariant for the material. Navier equation is used to formulate the problem in the differential equation form under plane stress condition. Displacement, stresses, and strains are obtained under the influence of material gradation and variable thickness. Three different material combinations are considered for the FGM disk. The mechanical response of disk obtained for different functionally graded material combinations are compared with the homogenous disk, and results are plotted graphically

期刊介绍： WSEAS Transactions on Applied and Theoretical Mechanics publishes original research papers relating to computational and experimental mechanics. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with fluid-structure interaction, impact and multibody dynamics, nonlinear dynamics, structural dynamics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
