  1. Barrier cracks cannot stop the extending of a fracture, and the strength of the sample is reduced by almost one magnitude because of the existing barrier cracks. there are great differences of ae distribution between specimens with non - penetrate crack and specimens with penetrate crack. as for penetrate crack, ae occurs near the two end of the crack, and for non - penetrate crack, crack, ae occurs near the two end of the crack, and for non - penetrate crack, ae occurs near the front edge of crack, which can be explained well by the theory of 3 - d fracture ; ae distribution near the outer part of collinear crack is similar with that of the end of penetrate crack, and inner part of collinear cracks will run - through with high loads

    關于預制系對巖石破的影響,集中討論了:空障礙體構造不能止主的擴展,反而會使巖石的破強度降低近一個量級;由於構造的不同,非穿透切口樣品和穿透切口樣品的聲發射空間分佈特點有本質區別,穿透切口樣品的微破在切口兩端發育,而非穿透切口樣品的微破在切口兩端之間切口前緣處發育,這用三維破理論可以很好地解釋;含共線構造的巖石,外端的聲發射分佈與單構造中端部的聲發射分佈相似,內端聲發射有密集分佈,在應達到一定水平時,內端部發生錯斷,而不是貫通。
  2. In the cohesive theory, fracture is regarded as a gradual process in which the separation of the incipient crack flanks is resisted by cohesive tractions. the relation between the cohesive tractions and the opening displacements is governed by a cohesive law

    內聚模型理論中,斷認為是一個漸變過程? ?初始兩側的分離受到內聚撓,內聚與張開量是由內聚關系確定的。
  3. In practical application, the m10 180 bolts, which are installed in the head cover of the torque divider of ts5560 special automobile, sometimes fracture all of a sudden. according to the tests of acceleration, stress and strain, and the exciting test, it is resonance vibration that leads to the compound - bending fatigue fracture of the bolts. the exciting force caused by drive system, transmitted through the torque divider, produces a 1000 - 1500hz cyclical excitation at the junction of the bolts and head cover, which causes the first order bending resonance vibration of the bolts

    通過加速度、應應變測試實驗和激振試驗的研究,發現ts5560特種車分動器取器氣缸端蓋m10 180螺栓斷問題是由於共振引起的雙向彎曲疲勞斷:傳動系統工作所產生的激勵,經過分動器結構的傳遞(特別是分動器一階扭轉模態的放大) ,在螺栓的連接處產生1000 1500hz的振動激勵,其導致螺栓一階彎曲共振,在螺栓一階彎曲模態的尼比較小的情況下,使得螺栓產生較大的共振響應,導致螺處的彎曲動應較大,疲勞壽命較低。
  4. Tial - based alloys with high specific strength are the most potential high temperature structural materials for aerospace application. however, the application of these materials is hindered by low resistance of damage, low room - temperature ductility and fracture toughness and high crack growth rate

    Tial基合金比強度高,是最具潛的航空、航天用高溫結構材料之一,但因其具有較低的抗損傷能,較低的室溫塑性、斷韌性和高擴展速率,這些斷特性礙了這種材料的應用,因而仍有必要研究其斷機理。
  5. The thermal fatigue resistance of al2o3 - 20wt. % tic is the best, it is due to high kic and pore of the material. the pore decrease the stress extension of tip of cracks and delay themal shock fatigue cracks extension. 4

    含20wt . tic的復合陶瓷具有高的k _ ( 1c )和較多的孔隙,這些空隙在熱震疲勞時降低熱震疲勞尖端的應集中並擴展從而提高了材料的斷,故其具有最好的抗熱疲勞性能。
