摘要
利用文献[1]的厚薄板通用广义协调元Coons混合曲面法分析了中厚板的振动,其优点是自由度少、精度高、程序简便、收敛快。算例计算出了四边简支方板的前几阶频率,其结果与文献[2]的结果符合良好。
The free vibration of moderate thick plate was analyzed by generalized conforming element and Coons surface approach for thick and thin plates in the literature^([1]).The generalized conforming element has many advantages such as less degree of freedom,high precision,easy to be programmed and rapid convergence.In addition,examples in this paper give the roots of the frequency of rectangular plate supported along four sides,the results are approaching to those of reference [2].
