摘要
本文从基本的平衡方程出发,导出了含边界条件的弹性力学差分方程;给出了平面问题、梁弯曲问题、薄板弯曲问题的具体形式和算例。这种方法能适应各种边界和荷载情况,而且放松了对位移连续性的要求。
From the basic equations of equilibrium, this paper presents the difference equations of e-lasticity, which includes the boundary conditions. The forms of plane problem, beam and plate bending problems are given as well. This method can fit the problems with any boundary and load, which also release the requirement for the continuity of displacement.
