Body Force Method (BFM) has been furnished a lot of useful and highly accurate solutions in practice since its development in 1967 by one of authors. Because BFM is based on the principle of superposition, it is easy to understand the basic concept of this method and introduce many inventions for getting highly accurate solutions in individual problems.Accordingly, many calculations using BFM has been done by special programs for individual problems. However, under the background of diversification and compexity of problems in recent years, the demand of a general purpose analysis program has increased more and more.Therefore, in this paper, the versatile analysis theory for two-dimensional elastic problems based on BFM are presented, and a lot of useful numerical results obtained by using a versatile program based on the theory are shown. All the numerical results were obtained by a standard personal computer.

自1967年开发以来，一位作者在实践中提供了许多有用且高度准确的解决方案。由于BFM基于叠加的原则，因此很容易理解该方法的基本概念，并引入了许多发明，以在单个问题中获得高度准确的解决方案。但是，在近年来问题的多元化和问题的背景下，通用分析计划的需求越来越多。因此，在本文中，提出了基于BFM的二维弹性问题的多功能分析理论，显示了使用基于理论的多功能程序获得的许多有用的数值结果。所有数值结果均通过标准个人计算机获得。
