Smoothed particle hydrodynamics (SPH) is a meshfree, Lagrangian particle method which has advantages in handling solids with extremely large deformation. Like any other numerical methods, cares must be taken to ensure its desirable accuracy and stability through considering several correction techniques in calculation. The selection of values for parameters in those correction approaches is a key...
A group of cell-based smoothed point interpolation methods based on the generalised gradient smoothing technique are proposed for the numerical modelling of saturated porous media. In the methods proposed, the problem domain is first discretised with the use of a simple triangular background mesh. The purpose of the background mesh is twofold: (i) it is used to select the supporting nodes for each...
