  1. A series of static and fatigue experiments which include lots of specimens are performed on bolted composite laminates that include different sizes, different lay orientations and different torques. dye - enhanced x - radiography is used to check the progressive damage process as evaluation techniques, which can be made nondestructively. finally, the ultimate strength and fatigue life of composite bolted joints in static tension and

    層合板接頭的試驗研究考慮了多種幾何尺寸、多種鋪層及不同擰緊力矩對其靜強度及疲勞性能的影響，同時使用滲透劑增強的x射線圖象技術對靜載和疲勞損傷擴展及累積過程進行了無損檢測，並對其進行了分析探討。
  2. Steel fiber scatters stress converging in the area of the top end of tiny cracks, restrict the occurrence and development of cracks, diminishes the width of cracks, and enhances the integrity of concrete with the occurrence of cracks via the effect of felting between concrete and steel fiber, and consequently the strength of concrete that resists compression, tension, and shear force increases obviously, and the capability of concrete that resists compact, and fatigue, and the ductility and durability of fissured concrete improve

    鋼纖維削弱了混凝土微裂縫尖端的應力集中、限制並約束裂縫的產生和開展、減小裂縫寬度、尤其是通過粘結作用提高了裂后混凝土的整體性，從而使混凝土的抗拉、抗彎、抗剪強度顯著提高，其抗沖擊、抗疲勞、裂后韌性和耐久性也有較大程度的改善。
  3. And two types of fatigue equations are put forward. according to them the fatigue stress coefficient of lcb for the concrete pavement structure and the structure coefficient of tension strength of lcb for the asphalt pavement structure are developed

    並提出了貧混凝土兩種形式的疲勞方程，據此推導了混凝土路面結構貧混凝土基層的疲勞應力系數和瀝青路面結構貧混凝土基層的抗彎拉強度結構系數。
  4. Results showed that the centrally notched laminates have an extraordinarily good fatigue performance, that they could survive more than 106 cycles under tension - tension load with high stress level without obvious damage. also, an experimental study on the residual strength after fatigue load was carried out

    含孔復合材料層合板的疲勞行為試驗研究結果表明，該復合材料含孔層合板具有優越的拉-拉疲勞性能，在高應力水平以下能夠經歷106以上的載荷循環，且無明顯目測損傷。
  5. The tension layer should have a very high tensile strength and anti - flexing fatigue strength ; the modulus of elasticity should be high

    抗拉層必須具有很高的抗拉強度和抗彎曲疲勞強度。
  6. Merely the fatigue strength in uniaxial tension or compression under constant - amplitude cyclic loading is given in the existing design code. the design result by using the fatigue strength in the code is apt to conservative under variable - amplitude or triaxial cyclic compression loadings, but sometimes apt to dangerous in uniaxial or triaxial tension - compression fatigue loadings

    現行規范中，僅有混凝土單軸、等幅波動拉伸和抗壓強度指標，採用這些指標進行設計，會導致設計結果有時偏於保守，如變幅及多軸壓疲勞；而有時又偏於危險，如單軸及多軸波動拉-壓疲勞。
