杂交有限条法及其在正交异性板上的应用

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。 

THE HYBRID FINITE STRIP METHOD AND ITS APPLICATION TO ORTHOTROPIC PLATE

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