FATIGUE AND CRACK-GROWTH ANALYSIS OF HYDROFOIL BOX BEAMS
Fatigue and crack-growth analyses are presented for seven hydrofoil-foil structures (box beams) tested at the David W. Taylor Naval Ship Research and Development Center. The box beams were constructed of materials and details representative of full-scale foil structures. All box beams failed before expiration of their designed duration. Results of the analyses indicate these procedures can be used to predict failure in the box beams. Stress-concentration factors and residual stresses were assumed in the fatigue analyses. Initial flaw sizes, based on nondestructive test techniques, were assumed in the crack-growth analyses.
