| 摘 要： | 梯度材料的广泛应用促进了梯度材料力学的深入发展。由于梯度材料在空间上渐变的特征。使得相应的力学行为与常规材料有较大的不同。文章分别就梯度材料力学中的细观模型、裂纹行为、热应力和数值计算方法等几个方面进行了阐述。回顾了近二十年来梯度材料力学所取得的研究成果和应用进展。最后探讨了梯度材料力学所面临的新课题及发展方向。

| Abstract: | With the extensive use of functionally graded material(FGM) in engineering fields,the mechanics about this kind of non-homogeneous material have been extensively developed in the recent years.Due to the graded properties of FGM in space,its mechanical behaviors are different from that of conventional materials.In this paper,the micro-scale model,fracture behavior,thermal stress and numerical calculation methods are reviewed.The research findings and application development of FGM mechanics in the latest two decades are also briefly discussed.At last,the coming challenges and the development direction of FGM mechanics in the future are tentatively presented. |
