The only quantifiable measure of fatigue damage is a crack . The fatigue strength therefore has to be determined from a fracture mechanical description of fatigue crack growth from an initial size to an unacceptable size .

For example a crack depth may be equal the wall thickness . This strategy can only be applied for elements with low importance with respect to structural redundancy . 2 ) plan inspection to find cracks before they exceed a grind ...

5, all along the crack, magneti- zeable particles are withdrawn from the mixture and concentrated along the cracks' edges. ... The accumulation of magnetized particles along the crack is surrounded by the "White Zone".
