A node-based smoothed conforming point interpolation method (NS-CPIM) for elasticity problems [PDF]
, 2011 This paper formulates a node-based smoothed conforming point interpolation method (NS-CPIM) for solid mechanics. In the proposed NS-CPIM, the higher order conforming PIM shape functions (CPIM) have been constructed to produce a continuous and piecewise ...

On the infinite particle limit in Lagrangian dynamics and convergence of optimal transportation meshfree methods [PDF]
, 2013 We consider Lagrangian systems in the limit of infinitely many particles. It is shown that the corresponding discrete action functionals Gamma-converge to a continuum action functional acting on probability measures of particle trajectories.

Application of the Godunov-Type Corrective Smoothed Particle Method to Impulsive Load Studies [PDF]
Journal of Applied Fluid Mechanics, 2022 The smoothed particle hydrodynamics (SPH) method is based on the kernel particle approximation, which is sensitive to the uniformity of the SPH particle distribution in the computational domain; that is, all SPH particles must be distributed evenly in ...

GIZMO: A New Class of Accurate, Mesh-Free Hydrodynamic Simulation Methods [PDF]
, 2015 We present two new Lagrangian methods for hydrodynamics, in a systematic comparison with moving-mesh, SPH, and stationary (non-moving) grid methods. The new methods are designed to simultaneously capture advantages of both smoothed-particle hydrodynamics

Phase-field modeling and simulation of fracture in brittle materials with strongly anisotropic surface energy [PDF]
, 2015 Crack propagation in brittle materials with anisotropic surface energy is important in applications involving single crystals, extruded polymers, or geological and organic materials. Furthermore, when this anisotropy is strong, the phenomenology of crack
