Why Pi is used in fracture mechanics?

01 January 1970 1 758 Report

I see a lot of equations work very well without Pi then it is needed to use Pi in fracture machines.

Pi (π) is not specifically used in fracture mechanics equations as a fundamental constant like it is in geometry or trigonometry. However, it may appear in some fracture mechanics equations due to the inherent geometry and mathematics involved in describing cracks and crack growth.
