Below the threshold stress intensity range, a crack

  • A.Grows at a constant rate
  • B.Grows faster than the Paris law predicts
  • C.Fractures immediately
  • D.Does not grow at any measurable rate

Answer: D

The threshold defines a stress intensity range below which growth is undetectable in practice. Designing so that service cycles fall below it is one route to a safe structure, though it is difficult to guarantee across a whole spectrum.
