摘要

功能梯度材料(FGM)是新一代的复合材料，它可以根据不同的加载环境用于不同的工程领域，但对其力学行为的研究需要复杂的数值和解析模型。文献中对这些模型进行了一些调查，然而，大多数调查都是基于简化的假设。在本文中，我们提出了功能梯度材料(FGM)梁在静荷载作用下的三维有限元模型。假定材料性能沿梁厚沿幂律分布连续变化，具有线性弹性特性。FGM梁采用C3D20R型六面体有限元(连续应力/位移，三维20节点，减积分)进行离散化。我们研究了几个FGM梁的数值算例，并将得到的数值结果与文献中解析模型的结果进行了比较。

Mechanical Response of Thin Composite Beams Made of Functionally Graded Material Using Finite Element Method

Functionally Graded Material (FGM) is a new generation of composite materials, it can be used for different engineering fields according to the loading environment, but the study of its mechanical behavior requires sophisticated numerical and analytical models. Several investigations in these models are available in the literature, however, most of those investigations are based on simplifying assumptions. In this paper, we present a three-dimensional finite element modeling of functionally graded material (FGM) beams subjected to static loading. Material properties are assumed to vary continuously along the beam thickness according to the power-law distribution with linear elastic behavior. The FGM beams are discretized by hexahedral finite elements type C3D20R (continuum stress/displacement, three-dimensional 20-node, reduced integration). We studied several numerical examples of FGM beams and compare the obtained numerical results with those of analytical models in the literature.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
