@article{oai:fukuyama-u.repo.nii.ac.jp:00007674, author = {上野谷, 実 and 中村, 雅樹}, journal = {福山大学工学部紀要}, month = {}, note = {P(論文), Tensile fatigue strength of smooth steel plates with circular holes is investigated. Ratios of the hole diameter to the plate width, D/W, are 0.125, 0.25, 0.5 and 0.75. The fatigue strength in S-N curve is expressed by applied stresses in gross sections and average stresses in minimum sections. In case of the applied stresses, the fatigue strength of the perforated plates with D/W ratios 0.125, 0.25, 0.5 and 0.75 is 0.54, 0.52, 0.37 and 0.14 times of the unperforated plates at 3×10^6 cycles respectively. For the average stresses, the fatigue strength of the perforated plates preserves 0.66~0.77 times of the unperforated plates regardless of the hole sizes.}, pages = {20--27}, title = {円孔を有する鋼板の疲労強度}, volume = {6}, year = {1984} }
