Abstract

A finite element model is constructed to analyze the effects of steady state temperature field on FGM layer thickness. The first-order shear deformation model is exploited to investigate the uncoupled thermal behavior of functionally graded plates in Abacus environment. The continuum is divided into 540 elements and 541 nodes using two node linear elements. The results show that the temperature distribution in the composite plate is more reasonable with increase in the thickness of FGM layer. The comparison with the non-graded two layered composite plate, the temperature field of the Zirconia/FGM/Aluminum three layered composite plate is in the form of a curve but in case of non-graded two layered composite plate the temperature field is in the form of inclined straight line with sharp bend at the interface of metal and ceramic phase.

Highlights

  • Graded materials (FGM) are microscopically inhomogeneous composite materials, in which the volume fraction of the two or more materials is varied smoothly and continuously as a continuous function of the material position along one or more dimension of the structure

  • To reduce stress and resist super high temperature, Functionally graded materials (FGM) have continuous transition from metal at low temperature surfaces to ceramics at high temperature surfaces because it is used widely in high temperature working environment such as aviation and nuclear reactor and so on, it is important to analyze the temperature and thermal stress field of the body made of the materials [1]

  • Yangjian et al [2] researched the effect of FGM layer thickness on temperature field by finite element method

Summary

INTRODUCTION

Graded materials (FGM) are microscopically inhomogeneous composite materials, in which the volume fraction of the two or more materials is varied smoothly and continuously as a continuous function of the material position along one or more dimension of the structure These materials are mainly constructed to operate in high temperature environments. FGMs have received considerable attention in the field of structural design subjected to extremely high thermal loading [7,8] Because it is used widely in high temperature working environment such as aviation and nuclear reactor, and so on, it is important to analyze the thermal stress filed of the body made of the material. The above research work, starting from the heat conduction law, will discuss the effects of steady state temperature field on FGM layer thickness and composition by using finite element method
