【摘要】 应用三维ANSYS/LS-DYNA软件实现滑石在落锤冲击过程的数值模拟,再现了单颗粒脆性材料在冲击破碎过程中应力变化及崩落现象,并与二维MCA数值模拟结果进行了对比。三维模拟结果有助于人们对冲击破碎过程的深刻理解和认识。更多还原

【Abstract】 3D ANSYS/LS-DYNA software is applied to implementing the numerical stimulation of talc during the process of drop hammer impact,which represents the strain change and spallation phenomenon of brittle material during the process of impact crushing. Then a comparison is made with 2D MCA numerical simulation results.The results of 3D simulation will contribute greatly to people’s understanding of this process.更多还原
