摘要
无拉力地基板的弯曲问题属自由边界问题。应用变分不等方程──线性互补方程求解自由边界问题已经证明是一种有效可行的解法。本文基于边界无法理论，建立了问题的边界元──线性互补方程，分析了无拉力Ｗｉｎｋｌｅｒ地基和弹性半空间地基上薄板的弯曲问题，数值算例说明了本文方法的正确性和高效性。
Variational Inequalites and linear complementary equation method have been proved to be a Powerful method for solving free-boundary problems and particularly the plate-bending with contact conditions. In this paper,the very important problems of the behaviour of plate on unilateral winkler and elastic half space foundation is treated by using boundary element-linear complementary equation.The numerical results, compared with those available analytical solution,show the efficency of this method.
