Abstract
Brittle fracture mechanics is classically thought of as operating under various restrictive premises, two of which seem both drastic and unrealistic: no crack will appear unless a crack is already present; cracks propagate along predefined trajectories. Our main goal is to do away with the above, while departing as little as possible from the sanctity of Griffith’s criterion. In a nutshell, the following will be achieved:
-
1.
crack initiation, and its subsequent evolution till complete failure of the loaded sample,
-
2.
complete freedom in the mechanical and geometric characteristics of the sample,
-
3.
boundary cracks,
-
4.
unilateral contact if needed.
