摘要 光滑粒子动力学(Smoothed Partic le Hydrodynam ics,SPH)方法是近年来得到广泛发展和应用的无网格方法的一个重要分支,它是一种纯Lagrangian方法。本文对现有的光滑粒子动力学方法进行了综述,介绍了该方法的理论基础、连续介质守恒方程、方法稳定性的改善等,重点阐述了边界条件的处理,并给出了SPH方法的算例。最后,介绍了SPH方法的最新进展状况。 The smoothed particle hydrodynamics(SPH) method is one of the most important branches of the meshless methods which are being developed and applied extensively, recently. It is a new and pure Lagrangian method. In this paper, the fundamental theory of SPH, the conservation equation of continuum mechanics, and the improvement of stability are introduced. Then boundary condition is emphasized. The example using SPH method is presented. Finally, the latest advances of the SPH is described and outlined.
