不同环境温度下孔隙率对FGM薄板挠度的影响
Influence of Porosity on Deflection of FGM Thin Plate Under Different Environmental Temperature
摘要
Abstract
The bending deformation of FGM thin plate with lateral loads is studied in different environmental tem-perature. The effects of environmental temperature on physical and mechanical properties is considered. Based on the elastic thin plate theory,the finite element method is used to solve the deflection value of the thin plate. The accuracy of the numerical calculation is verified by comparing with the existing literature results. The influence of the environmental temperature and material porosity on the deflection of FGM thin plate are discussed under differ-ent boundary conditions. The case-analyzing results show that: (1) The influence of temperature and porosity on the deflection of the FGM thin plate is significant. (2) When the porosity is constant, the deflection of thin plate increases with the increase of the environmental temperature;(3) When the environmental temperature is constant, deflection of thin plates increases with the increase of porosity parameter.关键词
