Abstract:
A way to determine conditions for the viscous-brittle transition preceding the fracture of a solid is suggested. The viscous-brittle transition is viewed as the result of competition between different fracture mechanisms. The model suggested in this work is valid in wide ranges of strain rates and temperatures. The temperature and strain rate intervals within which brittle fracture is most probable are calculated for several materials.
