摘要： 为了模拟固体在外力作用下产生的破裂现象，提出一种采用细分粒子的刚体破裂
的模拟算法。该算法首先将固体的四面体网格绑定到一系列离散的粒子上；再利用光滑粒子流
体动力学(SPH)对线弹性力学方程进行离散求解；并采用粒子细分的算法来进行开裂面的生成
和延展。最后实现了多个固体现象的模拟，如砖块碎落、砖墙受力倒塌等。文中算法可适用于
刚体脆性破碎的动画应用。

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.
