Non-Linear Elastic Theory of Rectangular Reticulated Shallow Shell Structures

摘要: 本文在基本假设的前题下,分析了矩形网格离散结构的变形以及变形量与内力之间的本构关系.在此基础上,通过建立等级模型,运用虚功原理推导出网格扁壳的作线性基本控制方程与边界条件.

Abstract: Based on fundamental assumptions,an analysis of the constitutive relations be-tween the internal.forces and deformations of discrete rectangular recirculated struturesis given.On the basis of this,an equivalent continuum model is adopted and the ap-plication of the principle of virtual work leads to non-linear governing equations and corresponding boundary conditions.
