梁板壳的概率变分原理

The Variational Principles of Probability about Beams,Plates and Shells

本文从最小势能原理出发,建立了梁、薄板及扁壳的概率变分原理及概率广义变分原理,它是建立概率有限元法、概率有限条法及概率样条函数方法的理论基础。

on the basis of the principle of least potential energy,the author of this paper establishes variational principles of probability and generalized principle for beame,plates and shallow shells,which may be served as the theoretical basis for the shaping-up of the finite element method of probability,the finite strip method of probability and the method of spline function of probability.
