摘要
本文根据薄板的广义变分原理,用有限元法对单向受压矩形板的屈曲状态进行了讨论,并用延续算法获得了在不同边界条件下的屈曲状态.
In this paper, based on the generalized variational principle of plates, the buckled states of rectangular plates under uniaxial compression are studied by use of the finite element method and the numerical analysis results under various boundary conditions are obtained by using the continuation calculation method.
