MOLECULAR DYNAMICS STUDIES OF BRITTLE FRACTURE OF SiO2

摘要：

By applying for molecular dynamics (MD) simulation and Griffith fracture criterion,the brittle behavior of crack extension of mode Ⅰ type is investigated.The critical stress intensity factor (SIF)KMDIc of crack extension is calculated,and the evolution of atoms near crack tip is observed.It is found that KMDIc is in good agreement with the Griffith fracture criterion KGriffith Ic.
