摘要：Smoothed particle hydrodynamics (SPH) was initially proposed by Monaghan and Gingold [1], and by Lucy [2] in 1977. SPH has progressed tremendously due to intensive theoretical work and computational improvements, particularly since the 1990s. This numerical method has been shown to be robust and applicable to a wide variety of fields. The main advantages of SPH come from its pure Lagrangian nature. The method can efficiently deal with the existence of large voids without special treatment. Also, the method can handle large deformations and extreme fragmentation without additional complicated or rather unphysical approaches. From a numerical point of view, its Lagrangian nature brings simplicity and parallelism to its algorithm. In addition, multiphase media can be easily described if the relationships between the phases are determined.
