中文摘要 | 因爲疲勞勁度資料,可以用來追踪複合材料疲勞損傷的情形,本研究提出一個疲勞殘餘勁度與殘餘強度關係的模式,在疲勞殘餘勁度遞減模式的基礎上,可以預測殘餘強度下降的統計分布情形。爲了驗證以上所提的模型是否可行,本研究使用文獻上已發表的實驗數據,以求得殘餘勁度、殘餘強度以及疲勞壽命的統計分佈,並且與實驗數據互相比較,結果顯示,理論預測與實驗數據有合理的相關。 |
英文摘要 | Fatigue residual stiffness degradation data can be used to track fatigue damages for composite laminates. This study proposes a relationship between residual stiffness and residual strength that a fatigue residual stiffness degradation model can be used to predict the statistical distribution of residual strength under a specific loading cycle. To verify the proposed relationship model, the statistical distributions of residual stiffness, residual strength and fatigue life are obtained theoretically for comparison with experimental data. This result indicates that the theoretical predictions agreed with the experimental data. |
