4. Conclusions Based on the results presented in this paper, one can conclude the following: • Minimum critical crack length value is far above the length of detected cracks (146 vs. 25 mm), so there is no danger of brittle fracture. • High cycle fatigue amplitude stress is far below values that should be considered for further analysis • Low cycle fatigue amplitude stress is not enough to reduce cover working life since it happens only 2000 times per year.
