摘要：

Fracture and subcritical crack growth characteristics under combined modes I and II loading were studied using the compact tension shear specimens of soda-line glass. The maximum normal stress criterion gives a good agreement with the experimental mode I-mode II fracture toughness envelope for initially straight cracks and kinked cracks. Subcritical crack growth characteristics were determined under sustained modes I and II loading in water. The values of K-I and K-II were calculated approximately by replacing the subcritical kinked crack with an assumed straight crack (a) over bar, and the K-Imax value based on the maximum normal stress criterion was used to describe this subcritical kinked crack growth. The experimental results show that subcritical crack growth under pure mode I, pure mode II, and various combined modes I and II loading can be well described by the K-Imax value based on the approximate maximum normal stress criterion.
