![]() In 2006, by using these developed methods, the following analyses were conducted. In 2005, Koshizuka and Matsuo improved MPS and SPH methods, respectively, while Noguchi developed the numerical algorithm of dual-scale and overlay meshfree methods. ![]() As the conventional finite element/difference methods cannot solve them, we adopted meshfree/particle methods. The main drawbacks of SPH are inaccurate results near boundaries and tension instability that was first investigated by Swegle. The advantages of the meshfree particle methods can be summarized as follows: They can easily handle simulations of very large deformations, since the connectivity among nodes is generated as part of the computation and can change with time 96, 97, 99, 227, 270, 279 The data structure of meshfree discretization can be linked more easily. were the first to apply SPH in solid mechanics. The objective of this research is to develop accurate analysis methods for fluid/structure interaction problems that structures undergo extremely large deformation. One of the earliest meshfree methods is smoothed particle hydrodynamics, presented in 1977. ![]() It provides a through examination of the advantages and disadvantages of various methods, with implementations and solutions techniques. We can simulate the fluid behavior with the particle. Meshfree and Particle Methods is the first comprehensive book on meshfree methods, providing an overview of the major methodologies that have been developed for solid and linear mechanics. Meshfree Method / Particle Method / MPS Method / SPH Method / Fluid / Structure Interaction / Biomechanics / Explosion Analysis / Finite Element Method / 計算力学 / シミュレーション / 構造・流体連成 A particle method is a is a method for fluid simulation that expresses fluid as groups of particles. KOSHIZUKA Seiichi The University of Tokyo, School of Engineering, Professor, 大学院工学系研究科, 教授 (80186668) The growing interest in these methods is due in part to the fact that they are extremely flexible numerical tools and can be interpreted in a number of ways. NOGUCHI Hirohisa Keio University, Faculty of Science and Technology, Professor, 理工学部, 教授 (70218303) Meshfree methods, particle methods, and generalized finite element methods have witnessed substantial development since the mid 1990s.
