中文摘要 | 本文主要探討積層板在螺栓接合側向鎖緊下之破壞及疲勞強度。積層板之開孔方式考慮鑽孔與環孔積層板二種。於破壞強度分析部分,本文採用二維平面應力與平面應變之新數值模擬分析方法,配合Hashin破壞準則來進行數值解析,與三維分析法比較,可大量節省計算時間。以本文之分析為例,大約為三維計算所需時間之二十至三十分之一,且分析結果與實驗相差不到10%。於疲勞強度分析部分,將疲勞實驗所得資料以統計與迴歸理論加以分析,比較及討論鑽孔與環孔積層板在不同側向鎖緊壓力下之疲勞強度。由實驗與分析結果可知,增加側向鎖緊度可提高積層板之接合與疲勞強度。且在開孔位置距離試片頂端較小(E/D=1)之積層板中,環孔積層板較鑽孔積層板有較高之接合強度,但E/D=3時,鑽孔積層板有較高之接合強度。 |
英文摘要 | The study presents the failure and fatigue strength of bolted joints in composite laminates with clamp-up effects. Glass-fiber woven-roving R800 composites are adopted here with circular holes of two types, drilled and moulded-in. In the failure strength analysis, a new method of combined two-dimensional plane stress with plane strain analysis was used to simulate the stress condition of composite laminate with bolted joint. The Hashin failure criteria was used in the failure analysis. Comparison with full three dimensional analysis, only 3% to 5% of computer time is needed for this method. And the results are within 10% different with experiments. In the fatigue strength, the date obtained from a series of fatigue experiments were approached by the statistical theorem in order to plot the S-N curve. From the numerical and experiment results, it is found that the higher the applied torque is, the larger of the bearing and fatigue strength of composite laminates. Whenever E/D=1, the composite laminates with molded-in holes have higher bearing strength than those with drilled holes, it is reverse as E/D=3. |
