摘要
文章提出了薄膜二维参变数模型,该模型描述了三种基本区域:张紧区、起皱区和松弛区。相应的参数变化规则也定义在二维参数模型之中。以二维参数模型和参数变化规则为基础,借鉴薄板大挠度问题中对板的中面的分析方法来分析薄膜结构,导出薄膜起皱问题三维数学模型的非线性协调方程。
A new two-variable-parameter （2-VP） membrane model is proposed, which describes the basic three states ： taut, wrinkle and slack of wrinkled membrane in a systematic format. A corresponding parameter variational principle （PVP） is then derived for this 2-VP membrane model. Based upon the 2-VP model and PVP, this paper analyses thin membranes structure referring to the method for analyzing the thin-plate middle plane about large deflection. Further more, A Nonlinear Compatible Equation for solving the Wrinkling problem of Thin Membranes is deduced.
