  1. Finally, an energy approach is combined with the fem in the simulation of the crack propagation along the fiber / matrix interface in a pull out process. the simulated results are in nice conformity with experimental results. the second part of the research deals with the characterization of the failure process in the fragmentation tests, which is one of the most frequently used test methods in studying thermal mechanical properties of fiber / matrix interfaces

    在這一部分工作的最後，採用能量法與有限元法結合起來，模擬纖維抽拔試驗中裂紋的擴展:針對以往研究工作中的不足之處，在模擬中使用能量釋放率，在表徵界面破壞時，所使用的應力強度因子考慮了纖維和基體兩種材料的不同屬性，並考慮裂紋尖端的單元奇異性，來研究裂紋長度和溫度對裂紋擴展的影響。
  2. Currently, the main methods used to measure the fiber / matrix interface properties of composite were based on micro - mechanics, including single - fiber composites fragmentation test ( sfc ), micro - debonding technique, single - fiber pull - out test, and single - fiber push - out test, in which sfc was most widely used

    目前直接用來測定纖維增強復合材料界面力學性能的主要微觀力學方法有單纖維復合材料斷裂實驗（ sfc ） 、微脫粘方法、單纖維拔出法、單纖維頂出法，其中以單纖維復合材料斷裂實驗的應用最為廣泛。
  3. Although numerical methods have frequently been used in the study of frc, theoretical analyses of such test methods as pull out tests and single fiber fragmentation tests, seemingly simple, remain to be challenging problems. problems arise when other factors are considered in connection with the various numerical models. these factors include nonlinearities in the properties and / or geometries of the materials, influences of such environmental conditions as temperature ( which is also to be studied in the present work )

    本論文正是針對以往研究中的不足，在對纖維增強復合材料破壞問題進行數值模擬的研究中，綜合考慮了纖維和基體材料的非線性效應、纖維和基體材料受外載發生大變形時的幾何非線性，以及纖維基體之間界面脫粘時接觸單元的非線性效應。
  4. At first, large numbers of tests have been done to test seeds " fragmentation ratio. then, the other performances are measured by an apparatus in right range of fragmentation

    測定其排種時的破碎率，分析嚴生破碎的原因，並在破碎率小於0 . 5的轉速范圍內檢測排種性能的各項指標。
  5. The cohesive theory has proved effective in the simulation of complex fracture processes including : the fragmentation of brittle materials ; dynamic fracture and fragmentation of ductile materials ; and the dynamic brazilian test for concrete

    已證實此理論對復雜的斷裂過程的模擬是有效的，包括：脆性材料的斷裂、韌性材料的動態斷裂和破碎、混凝土的動態bazilian測試等等。
  6. Simultaneity, various single fiber strength tests ( sft ) and the single fiber fragmentation techniques were discussed, and the influence of fiber surface treatment on the single fiber strength and the interface load - transfer were discussed in detail. the two parameters weibull statistic theory was used to evaluate the scattering of the tensile strength test results of three types of single fibers with different surface treatments. the following conclusions can be drawn based on the analysis of the results

    同時，文中詳細討論了單纖維強度測試實驗（ sft ）和單纖維復合材料斷裂實驗（ sfc ） ，重點討論了纖維表面處理對單纖維拉伸強度和界面載荷傳遞能力的影響；採用兩參數weibull統計理論對經過三種不同表面處理的單纖維拉伸強度的測試結果的分散性進行了評價，獲得了理想的實驗結果；分析實驗結果可得到如下結論， sft實驗與sfc實驗獲得的界面剪切強度吻合良好；經過表面處理的玻璃纖維的界面粘結情況較未經處理的玻璃纖維好；經過表面處理的玻璃纖維的界面粘結強度和單纖維拉伸強度均高於未經表面處理的玻璃纖維。
