The present study provides closed-form expressions of propagation (kinking) angles by generalizing maximum energy release rate criterion in linear elastic fracture mechanics (LEFM) within micropolar theory of elasticity to address the in-plane, brittle crack propagation phenomenon in size-dependent materials with the presence of particle rotations.

微极连续体中准脆性裂纹扩展的基于能量的断裂准则:分析和数值研究



本研究通过在微极弹性理论中推广线性弹性断裂力学 (LEFM) 中的最大能量释放速率标准来提供传播(扭结)角度的闭式表达式,以解决存在粒子旋转的尺寸依赖性材料中的面内脆性裂纹扩展现象。
