- 論文の詳細を見る
The stress distribution near a crack tip and crack propagation in a β-silicon nitride crystal are investigated by molecular dynamics(MD)simulations. A crack propagates when K_I is greater than 0.7 MPa√<m>. On the other hand, it shrinks when K_I is smaller than 0.65 MPa√<m> indicating that the K_<IC> value is about 0.7 MPa√<m>. This value agrees well with that caluculated using Griffith's theory. The stress distribution near the crack tip for K_I is 0.7 MPa√<m> i.e.the case when the crack stops, is calculated from the MD results, assuming that the stress is the average of the atomic stresses. The calculated stress distribution is in good agreement with the linear elastic solution.
