What is it about?
The behavior of notch cracks under the effect of a borehole was studied and described frequently. However, the Fracture Analysis Code, Franc2D, has no fluid parameters, and the behavior of crack propagation was satisfied with experimental work. The results were also verified with some expression of the stress intensity factor (SIF) and energy release. As compared with Geocrack, Franc2D has advantages in computing SIF and G. Also, Franc2D has a preprocessor program called Casca that can simulate a variety of geometry.

Why is it important?
Using Franc2d in the simulation of cracks in rock as a brittle material. FE analysis was verified, and stress intensity factors have been calculated.
Perspectives
The first using of Franc in Rock simulation. the calculation of fatigue life in rock as based on linear elastic fracture mechanics.
