论文摘要
我们提出了一种基于粒子内能量景观的计算来模拟粒子碎片化的方法。使用损伤和断裂力学原理根据内部应力来计算应变能的景观。景观S脊的数值计算用于确定断裂标准以及后破坏片段的形状。该方法提供了对颗粒材料中断裂效应的基于物理的理解。
We propose a method for the simulation of particle fragmentation based on the calculation of the energy landscape inside the particle. The landscape of strain energy is calculated in terms of internal stress using the principles of damage and fracture mechanics. Numerical calculation of the landscape s ridges is used to determine the breakage criterion as well as the shape of the postbreakage fragments. This method provides a physical-based understanding of the breakage effect in granular material.
