Is it a problem that the stress intensity factor, K, from Irwin's near-tip approximation approaches infinity as you get close to the crack tip and approaches zero as you get too far away from the crack tip? Give a brief reason why or why not.

Answer:

No it is not a problem

Explanation:

It is not a problem because the stress intensity factor K would approach infinity as you get close to a crack tip and the intensity factor would approach Zero as you get too far away from the crack tip and this is simply because a crack is a notch with zero tip radius .

and The application of stress intensity factor k in respect to present fatigue crack tip is termed " linear elastic fracture mechanics "
