| Abstract(J) | 疲労限度や寿命は負荷方式によって異なり，応力集中によっても大きく影響される．平均応力の影響はいくつかのモデルを用いて数学的に表現されているが，実験データに基づくと，Walkerモデルが最も適切であり，高い予測精度を有することが示された．溶接による組立応力が疲労限度に及ぼす影響や，下限界応力拡大範囲についても同様であった． Translation |
| Abstract(E) | The fatigue limit and lifespan vary depending on the loading mode and are also greatly affected by stress concentration. The effect of mean stress has been mathematically expressed using several models, but based on experimental data, the Walker model has been shown to be the most appropriate and to have high predictive accuracy. The same was true for the effect of assembly stress due to welding on the fatigue limit and the threshold stress intensity range. |
