摘　　要：本文建立的半解析单元法不用任何刚度矩阵的概念.本方法将给定的弹性体划分为各个单元,并对每个单元分别选定自己的试函数,此试函数满足边界条件和连续条件.本文所提出的方法可广泛的用于解非线性问题和其它问题。In this paper a Semi-Analytical Element Method has been suggested, which is unique in that concepts of stiffness matrix are dispensed with. In this method the given elastic body is subdivided into its imaginary jndividual components or 'elements'.For every element some trial functions are adopted. At given points the trial functions have to satisfy the boundary conditions and continuous conditions. The suggested method may be widely used for solving nonlinear problems of solid mechanics and other types of problems.
