| Abstract: | Smoothed particle
hydrodynamics (SPH) is a Lagrangian meshfree particle method, and
has been widely applied to different areas in engineering and
science. SPH method uses a set of particles to discretize the
computational domain and to represent the state of the system
being modeled, and approximates the governing equations based on
the set of particles. This paper provides an overview on the
development, numerical aspects, and applications of the SPH
method. The basic concepts, consistency, boundary treatment,
stability and computational efficiency of the SPH method have been
discussed. Applications of the SPH method to compressible and
incompressible fluid flows as well as to rapid deformation and
failure of elastic-plastic materials have been addressed. Finally
the paper concludes with remarks of the merits and defects of the
SPH methods, and with some predictions of numerical method
development and application areas. |
