具有旋转自由度的广义协调矩形膜元

GENERALIZED CONFORMING RECTANGULAR MEMBRANE ELEMENT WITH DRILLING FREEDOMS

    摘要
  • 摘要: 本文根据广义协调的思想,在平面应力矩形单元双线性协调位移场中,引入附加广义泡状位移场,构造出一种具有平面内旋转自由度的矩形膜单元,它满足广义协调条件。数值计算结果表明,这种单元有很高的计算精度,而且计算量少,是一种能收敛于精确解的单元。

     

    Abstract: Based on the concept of generalized compatibility, a rectangularmembrane element with drilling freedoms is formulated by introducinga generalized bubble displacement field on the basis of the bilinear conforming displacement field. Numerical results show that the present element converges and is well behaved.
