| 摘 要： | 从细观力学角度出发根据材料细观组分分布对具有不同复杂形状功能梯度材料构件进行三维动力特性分析,并相应给出其三维固有频率及其基频对应的位移振型和应力振型沿厚度方向的三维分布。结果发现对同样材料细观组分分布的不同功能梯度结构,其固有频率和相应的振型分布均有很大差异。此结果为建立专门的功能梯度板壳理论提供定量的资料依据。

| Abstract: | According to the micromechanics method,the three-dimensional dynamic characteristics of functionally graded material structures with different complex shapes by the material component determined in the process of the material production were analyzed,and the three-dimensional distributions along the thickness direction of the natural frequencies and the corresponding to displacement and stress modes were given.The result shows that there are great difference of natural frequencies and the corresponding mode shapes of the different functionally graded structures with the same material microcomponent distributions.The basis of quantitative data can be provided by these results for the specialized functionally graded plates and shells theory. |
