Primes¶
- Fracture Toughness
- … out of the energy balance: the crack runs when the energy released per unit advance exceeds the energy absorbed, which the stress-intensity factor $K = \sigma\sqrt{\pi a}$ captures — once $K$ reaches the material's fracture toughness $K_{IC}$, propagation becomes catastrophic; below it, the crack is stable.
This sourceIntroduces the stress-intensity factor K and the critical fracture toughness K_IC as the threshold separating stable cracks from catastrophic propagation.
