| 摘 要： | 功能梯度材料的宏观材料特性在空间上是连续变化的,因此即使在线弹性理论范围内,由于控制偏微分方程是变系数的,相应的力学分析具有很大的挑战性.综述了功能梯度材料与结构若干力学问题的最新研究进展,包括功能梯度材料梁、板、壳结构的解析解与半解析解以及简化理论的研究、功能梯度材料结构的数值计算方法研究、功能梯度材料的断裂力学研究.最后对未来功能梯度材料与结构的力学研究进行了展望.

| Abstract: | Owing to the continuously varying characteristics of macroscopic material properties of functionally graded materials (FGMs), the governing partial differential equations, even within the framework of linear elasticity, are those with variable coeffcients, making the mechanics study a tough challenge. This paper gives a survey on the recent advances in the study on functionally graded materials and structures. We focus on the following three aspects: (1) the analytical and the semi-analytical solutions of f... |
