内容摘要

Chapter 1 Introduction

　　This chapter introduces the concept of functionally graded
material (FGM and presents a brief review of recent developments in
modeling and analysis of FGM structures.

　　1.1 Functionally Graded Materials

　　Functionally graded material (FGM is a novel concept in
material design and manu- facture in which the volume fractions of
material constituents vary continuously with spatial positions. The
concept of FGM was first proposed by Japanese scientists in 1984 for
preparing thermal bamer coatings [1， 2]. Initially， FGMs were made from a
mixture of ceramics and metal， or a combination of different metals.
The brittle ceramic constituent of the mixture， with low thermal
conductivity， provides high-temperature resistance， while the ductile
metal constituent prevents the onset of cra at stress concentration
sites caused by rapid development of a high temperature gradient. The
advantage of FGM is that no distinct internal boundaries exist， and
failures due to interfacial stress concentrations developed in
conventional components can be avoided. Featuring gradual transitions in
their microstructure and composition.FGMs are designed to meet
functional requirements that vary with the position of a structure
component， and to optimize the overall performance of the component. As a
new concept in material design， FGMs have found immediate or potential
applications in the aerospace， electronics， chemical， optics， and
biomedical industries [3， 4].

　　Although the concept of FGM is new in the industrial field，
these materials exist extensively in nature. Some examples of natural
FGMs are shown in Fig. 1.1. Bones， skin， and the bamboo tree have graded
microstructures and display obvious graded material properties.
Generally， artificially produced FGMs are composed
