The parametric study manifests that the variance of nonlinearity coefficient has more serious effect on orthotropic plate than on quasi-isotropicplate.
参数研究表明非线性系数的变化对正交各向异性板的影响较大，而对准各向同性板的影响较少。

A new calculating method for solving orthotropic plates is presented in the paper. The orthotropic plate is dealt as a equivalent isotropicplate with ribs.
本文提出一种求解正交各向异性板的新的计算方法，使之等效为各向同性加肋板。

This paper discusses the inequality of the upper and lower bounds of the limit analysis of an isotropicplate with equal thickness when it is subjected to the action of various loads.
