Conclusions
-
1.
Limitations were derived for functions entering into relations obtained earlier to describe the behavior of isotropic graphite materials under load. It was shown that empirical curves conform to these restrictions.
-
2.
The proposed relations were used to determine stress distribution at the tip of a normal-rupture type crack under plane stress conditions. In conclusion, the authors thank Yu. N. Rabotnova for discussing the work with us.
