Abstract Accurate simulation of the single-particle breakage plays an essential role in studying and understanding the behavior of crushable granular materials. Peridynamics has a significant advantage in the simulation of particle breakage owing to its treatment of discontinuities and fractures. This work simulates the single-particle breakage by peridynamics. The particle breakage patterns and the force-displacement curves are focused under different material point discretization schemes, viz. regular discretization scheme, modified regular discretization scheme, hexahedral element converted discretization scheme and random-packing discretization. The result shows that the material point discretization scheme has a great influence on the breakage patterns while less impact on the maximum contact force. Besides, a program for extracting the fragments from the failure bond data is provided to offer an inside vision of breakage patterns.

单粒子破碎模式对使用近场动力学离散化的依赖性

摘要 单颗粒破碎的精确模拟对于研究和理解可压碎颗粒材料的行为具有重要作用。由于近场动力学对不连续性和裂缝的处理，近场动力学在模拟颗粒破碎方面具有显着优势。这项工作通过近场动力学模拟单粒子破碎。粒子破碎模式和力-位移曲线在不同的材料点离散化方案下集中，即。正则离散化方案、修正正则离散化方案、六面体单元转换离散化方案和随机包装离散化。结果表明，材料点离散化方案对断裂模式影响较大，而对最大接触力影响较小。除了，
