The aim of this chapter is to provide an in-depth presentation and survey of meshfree particle methods. Several particle approximations are reviewed; the SPH method, corrected gradient methods, the moving least squares (MLS) approximation, and maximum-entropy approximations. The discrete equations are derived from a collocation scheme or a Galerkin method. Special attention is paid to the treatment of essential boundary conditions. Finally, different approaches for modelling discontinuities in meshfree methods are described, including peridynamics and phase-fields.
