A simple and efficient 4 mode quadrilateral shell element presented herein is obtained by combining the Mindlin plate bending element and the membrance element with drilling degrees of freedom. The shell element has six degrees of freedom per node, which allows easy modeling of complex shell surface sections and compatibility with other elements with rotation degrees of freedom. The element passes the patch test, and has no spurious zero energy modes and locking. Very good results have been obtained for thin and thick plates and shells. The element mentioned above has broad prospects of application.

提出了一种简单有效的四边形平板壳元,它由基于Mindlin板理论的平板弯曲元与带有平面内转动的平面膜单元组成.单元中每个结点有六个自由度,易于模拟复杂的壳面连接和易于与别的带有转动自由度的单元相容.此种板壳元能顺利通过弯曲、膜小片检验,无剪切和膜“锁住”及多余零能模式,计算方法简便,适用范围广,且计算精度十分理想,具有广泛的应用前景

A general and efficient element is discussed for elasto plastic analysis of plates and shells. This element has six degrees of freedom per node, and is obtained by combining the Mindlin plate bending element and the membrance element with driling degree of freedom. The layered model is used for elasto plastic analysis in the thickness direction. The results of numerical examples show that the present method is feasiable and reliable.

Based on the arbitrary-Lagrangian-Eulerian descriptions for a rigid oscillating body and by using the moving mesh technique,the fluid field around the ideal thin plate(ITP) in sinusoidally heaving or pitching motions was simulated by numerical method.After evaluating the total work acting on the ITP by the airflow during an oscillating cycle,the flutter mechanism of the ITP was discussed.Results showed that flutter instabilities would not occur for the ITP with only one degree-of-freedom.With the identified...

Based on the arbitrary-Lagrangian-Eulerian descriptions for a rigid oscillating body and by using the moving mesh technique,the fluid field around the ideal thin plate(ITP) in sinusoidally heaving or pitching motions was simulated by numerical method.After evaluating the total work acting on the ITP by the airflow during an oscillating cycle,the flutter mechanism of the ITP was discussed.Results showed that flutter instabilities would not occur for the ITP with only one degree-of-freedom.With the identified flutter derivatives of the slotted ITP with slot ratio of 20%,a twodegree-of-freedom flutter analysis was performed based on an assumed long-span bridge.In addition,numerical simulations were also carried out to investigate the flutter mechanism of the slotted ITP.It was found that a central slot on the ITP could largely reduce the total work acting on the ITP by the airflow,and a certral slot made the ITP more stable against flutter.

基于任意拉格朗日-欧拉描述法及刚性模型和计算网格同步运动的动网格技术,数值模拟了作竖弯或扭转谐振动的平板绕流场.通过计算一个运动周期内作用在平板上的总功,分析了理论平板的颤振机理.研究表明仅有竖弯自由度或扭转自由度的平板不可能发生单自由度颤振.计算了中央开槽20%平板的颤振导数.通过对一设想的大跨度桥梁进行二自由度颤振分析,显示平板中央开槽能显著提高其颤振稳定性.最后从气动机理上解释了平板开槽能提高颤振稳定性的原因.
