弹性空间问题的虚拟域法

The Virtual Area Method of Elastic Problems

本文将弹性力学的空间问题,假想置于相同介质的无限域中,并以无限弹性空间的Kelvin解作为影响函数.在问题的边界上配点计算出有限个影响函数值。域内点的应力、位移可由这些影响函数叠加求得.

In this article, the finite area space problems of elastieity are supposed as infinite area space problems in the same medium, and the Kelvin solution of infinite area is taken as the influnce function. The limited values of influnce function are calculated at the boundary collocated points of the problem. The stress and strain of the points in the area can be obtained by the superposition of these influnce function values.
