摘要
本文以文[1]构造的拟协调板弯曲单元为基础,横向剪切应变假设中采用沿厚度二次分布,将其应用于薄板固有振动分析,求解前n阶固有频率,结果表明该单元具有良好的数值特性。
Quasi-conforming plate bending element formed by the paper[2] is applied to the thin plate vibration analysis. Inherent frequencies for the first n steps are solved. The results are presented to illustrate that the element is reliable.
