杂交有限条法及其在正交异性板上的应用

THE HYBRID FINITE STRIP METHOD AND ITS APPLICATION TO ORTHOTROPIC PLATE

  • 摘要: 本文建立了一种杂交有限条法,并应用于各向同性板和各向异性板。这工作是基于修正余能原理进行的。在有限条列式的过程中,在条中假设应力场而在条的边界上假设位移场。数值计算表明,过种方法是合理的,能较快地逼近准确解。

     

    Abstract: On this paper,a stress version of the hybrid finite strip method is established and applied to orthotropic and isotropic rectangular plates. This work is based on the modified complementary energy principle. On the formulation of hybrid finite strip,the streess in the strips and the displacements at the boundaries between the strips are assumed. Numerical examples demonstrate that the proposed method is reasonable and convergent rapidly to the exact solution.
