离散元应用论文 Based on the Particle Element Method, a meso-scale dynamic model is developed for numerical study of the dynamic failure behavior of three-phase concrete i.e., aggregate, mortar, and interface, under different strain rates. First, a pre-proc

受刀尖径向总跳动度影响的介观尺度切削厚度模型研究，卢晓红，贾振元，瞬时切削厚度模型的计算精度直接影响介观尺度切削力模型预测精度。现有介观尺度切削过程中的瞬时切削厚度模型大多基于刀尖摆线运
