摘要

The paper by Lee et al. (2009) applies the original version of the MPS (Moving Particle Semi-implicit) method (Koshizuka and Oka, 1996) to the simulation of slamming-induced impact pressure. Based on a simulation-experiment (Chung et al., 2007) comparison, the authors conclude that the original MPS method is able to accurately simulate the impact loads and pressures. However, a number of previous papers have clearly shown the drawbacks of the original MPS method that would make it practically inapplic able to the prediction of impact pressures. Therefore, the main conclusions of this paper are in clear contrast to those in previous papers. Further, the experimental data reported by the authors and used for comparison and validation are not consistent with those by Chung et al. (2007). The inconsistencies between the reported and original experimental data would add more doubts to the statements/conclusions by the authors (Lee et al., 2009).
