Abstract: To simulate the brittle fracture when the solid is influenced by the external force, a method
on modeling brittle fracture is proposed. Firstly the tetrahedral mesh of the solid model is bound to a
series of particles. Then the smoothed particle hydrodynamics (SPH) is used to solve the equation of
linear elasticity, and a subdivided scheme is adopted to generate the fracture surface. Finally, the
rendering of some scene of the brittle fracture is achieved, including brick falling, brick-wall collapsing.
This method can be applied for simulating the brittle fracture of solids.

Key words: simulation of brittle fracture, smoothed particle hydrodynamics, particle system
