| 摘 要： | 基于任意多边形网格邻域可变技术,提出一种针对多介质带有间隙计算模型的闭穴滑移计算方法,实现了复杂工程中带有间隙问题的数值模拟.该方法避免了传统算法中以直代曲的缺陷,克服了传统方法由于网格扭曲变形带来的接触点求解的困难.数值模拟结果验证了方法的可行性,体现了算法对间隙闭穴的无缝连接特点.

| Abstract: | We present a closed void interface method for computational models with void interface in multi-material problems.It simulates void successfully in complicated engineering.It bases on a technique of changeable mesh topology.It avoids using a straight line to replace a curve in traditional method,and overcomes difficulty in solving contact points.Numerical simulations confirm that the technique is effective.It shows characteristic of no void connectivity. |
