  1. At room temperature, the fracture for r specimen is the characteristic of fatigue stripe, while tire - like pattern appears on the fracture of the t specimen, and the hydrided sample is characterized by skeleton - like pattern and quasi - cleavage fracture at room temperature. however, the fracture characterized by second - crack at 400

    常溫下, r向試樣的低應變幅疲勞斷口上較為明顯的特徵是疲勞條紋的存在; t向試樣的疲勞裂紋擴展區斷口上則為輪胎痕花樣;滲氫態試樣室溫下疲勞斷口的主要特徵為脊骨狀花樣和準解理斷裂特徵。
  2. Based on a large numbers of model / simulation test of the intermittent cracked rock - like samples, fatigue strength, fatigue deformation and crack appear in preexisting cracks tips, the growth of crack, the pattern of crack coalescence are studied / analysed systemically by means of cyclic load and static load, in the course of the model test, the difference between cyclic load and static load of crack appear in preexisting cracks tips, the growth of crack and the pattern of crack coalescence are observed and analysed

    在試驗過程中,觀察並分析了循環加載方式下,預置裂隙端部裂紋萌生、擴展、巖橋貫通模式與靜載方式下的差異;探討了疲勞裂紋萌生、擴展的機理,分析了加載頻率、荷載水平對裂隙試樣疲勞強度、疲勞變形(總變形和不可逆變形)的影響規律。
