Effect of rock shapes on brittle fracture using Smoothed

Feb 01, 2010 · Smoothed Particle Hydrodynamics (SPH) method SPH is a mesh-free numerical method that is used to obtain solutions to systems of partial differential equations. The problem geometry is discretised into particles that represent specific material volumes. Impact modeling with smooth particle hydrodynamics - Smooth Particle Hydrodynamics (SPH) can be used to model hypervelocity impact phenomena via the addition of a strength of materials treatment. SPH is the only technique that can model such problems efficiently due to the combination of three dimensional geometry, large translations of material, large deformations, and large void fractions for most problems of interest.

Smoothed-par­ti­cle hydrodynamics ( SPH) is a com­pu­ta­tional method used for sim­u­lat­ing the me­chan­ics of con­tin­uum media, such as solid me­chan­ics and fluid flows.

SPH, introduced by Gingold and Monaghan and reviewed extensively by Liu and Liu and Monaghan, (1992, 2005, 2010), is a meshfree method for simulating fluid flows using moving particles, each of which represents a given volume of fluid. These particles interact with other nearby particles, and their movement represents the fluid flow.
