We propose a method for the simulation of particle fragmentation based on the calculation of the strain energy field inside the particle. The topography of strain energy is calculated in terms of internal stress using the principles of damage and fracture mechanics. Numerical calculation of the energy field’s ridges is used to determine the breakage criterion as well as the shape of the post-breakage fragments. This method provides a physical-based understanding of the breakage effect in granular material.

基于应变能场的粒子破碎

我们基于粒子内部应变能场的计算，提出了一种模拟粒子破碎的方法。应变能的形貌是根据内部应力使用损伤和断裂力学原理来计算的。能量场脊的数值计算被用来确定断裂准则以及断裂后碎片的形状。这种方法提供了基于物理的颗粒材料破损效果的理解。
