  1. The method for measuring the plane strain fracture toughness klc has been introduce to high polymer bonded explosives ( pbx ) by systematically studying technologies concerning the shape of specimen, the depth and its machining of crack, the loading rate, the measurement of critical fracture load, and the computation of klc, etc. the method has been used to test and study klc of three typical high polymer bonded explosives which are j2, jl, j3 respectively both at normal temperature and unmoral temperature

    本文以高聚物粘結炸藥為研究對象,對測試高聚物粘結炸藥的平面應變斷裂韌度所涉及的樣品形狀、裂紋深度及裂紋制備、加載速度、臨界斷裂載荷p _ q的確定及平面應變斷裂韌度k _ ( ic )的計算等方面進行深入研究,建立了較為完善的炸藥平面應變斷裂韌度測試方法。
  2. A general consensus exists related to the influence of slow crack propagation ahead of the crack tip upon the nonlinearity observed in the typical load - deflection response of the concrete specimen, namely, concrete exhibits somewhat quasibrittle behavior, which has been verified by the inapplicability of the conventional linear elastic fracture mechanics ( lefm ) and fracture models suitable for metal - like materials

    現在已經意識到,混凝土在其典型的位移曲線中呈現出的非線性特徵是由於裂縫在端部的緩慢擴展引起的,可以認為是混凝土的一種半脆性性能。這是在發現傳統的線彈性斷裂力學( lefm )和適合金屬類材料的斷裂模型不適用於混凝土研究時得出的結論。
  3. This paper, based on collecting many empirical determinations of strength parameter for jointed rock masses all over the world, puts forward the improved empirical determination of strength parameters, that is to say, " size effect reduction factor " and " jointed rock reduction factor " of the intact rock specimen for the study on jointed rock mass strength parameter, and applies to the a typical location of the dam, which proves that this methodology is feasible and rational, and a new way for study of strength parameter in jointed rock masses is established

    在大量收集國內外節理巖體強度參數經驗確定方法的基礎之上,提出了改進的節理巖體強度參數經驗的確定方法,即對完整巖石進行「尺寸效應折減」與「節理化折減」的二次折減法,並應用於某壩址區工程實例中,所得的計算值與現場實測抗壓強度值接近,較以往的經驗確定方法更加準確,證明了節理巖體強度的降低是尺寸效應與節理化綜合作用的結果,為節理巖體強度參數的研究提供了一條新的思路。
  4. Specimen of typical hard spot in aluminum alloy die casting is analyzed. the cause for formation of hard spots is discussed and effective methods to prevent hard spot are proposed

    切削加工鋁合金壓鑄件時,經常會碰到硬質點打刀現象,嚴重影響刀具壽命和加工質量,針對這個問題,對壓鑄件中出現的典型硬質點取樣分析,探討了硬質點的形成原因,並提出了有效的解決措施。
