Hole perpendicularity
Nettet3. mai 2024 · Hole perpendicularity in dry and cryogenic tests was similar; the use of cryogenic cooling did not seem to have any impact. However, it was observed that in general, the average perpendicularity in cryogenic tests was slightly lower than their counterparts in dry tests.

Nettet23. sep. 2024 · The perpendicularity error in the 0° direction will greatly reduce the high-cycle fatigue and the impact on the low-cycle fatigue is relatively small, while the error in the 180° direction is just the opposite. The fatigue life is negatively correlated with the angle of the perpendicularity error.
