本文在面力不连续点处,提出虚单元法,解决了因不连续点而引起的误差。此方法不但精度高,而且可直接应用于处理多连域问题。本文编制了一组二维弹性平面问题程序。并给出了算例。 This paper proposes the imaginary element method at the discontinuous point of the surface force and resolves the error caused by the discontinuity. This method is not only accurate, but it can also be applied directly to multi-domain problems. This paper has developed a set of two-dimensional elastic plane problems. And gives an example.
