  1. The alternative defensive ability of structures refers to their ability to adjust the internal forces automatically to avoid the continuation of damage and maintain the whole structure stability when local members failed unexpectedly due to abnormal events or severe local overloading

    摘要結構的二次防禦能力是指結構因突發事件或局部嚴重超載而造成部分構件突然失效時，結構自行調整內力、阻止破壞過程的延續、保證結構不發生整體破壞的能力。
  2. Author thinks that the direction of the maximum plastic distortion along a constant radius around the crack tip may be considered as the direction of shear - mode fracture ( named pmax - criterion ) and the load when located shear band prongs the ligament in the front of crack tip is regarded as the limited load of shear - mode fracture. ( 3 ) the fad ( fracture assessment diagram ) of titled crack is proposed based on achievements of mesomechanics about i - ii complex ductile fracture of metal, and the titled crack is classified two kinds : void - mode fracture is assessed by fracture assessment curve, and shear - mode fracture by limited load. ( 4 ) using a fe program based on plantle - ressue theory to calculate some mesomechanical parameters, a flange joint structure of a high pressure vessel ( design pressure 31. 4mpa and the thickness of the hemispherical head is half of that of shell. ) is analyzed to determine whether the structure under operation pressure is safe or not, forecast the mode of potential invalidation and argue for the rationality of design of the structure

    試件的整體斷裂為剪切型，但在試件芯部裂尖鈍化區中部出現了韌窩型啟裂並有一定的擴展，說明局部較高的應力三軸度也會使韌窩型機制得以發展，但是不改變試件整體的剪切型斷裂模式；對韌性斷裂的剪切模式的細觀機理做了一定的探討，並且提出了含裂紋構件剪切型斷裂的宏觀判據：認為裂紋前方的集中剪切帶中與裂紋尖端等半徑處最大有效塑性應變出現的方向可以作為裂紋剪切斷裂的方向（可簡稱為_ （ pmax ）準則） ，集中剪切滑移帶貫穿裂紋前方承載韌帶時的載荷可以作為極限載荷；本文運用金屬韌性斷裂細觀力學在一復合型韌性斷裂方面的研究成果，採用失效評定圖的形式，提出了傾斜裂紋的安全性評定方法的基本框架。
  3. It also studies the influencing factors including sampling frequency, pd waveform, decline time, time intervals between pd pulses, mother wavelet, center frequency of interference, entropy threshold value and snr. in addition, it applies wavelet packet method （ wpm ） for non - stationary signal de - noising in on - line pd monitoring and analyzes the processing results under different pd waveform, sampling frequency and noise level. firstly, the curve of pd

    基於小波包變換的非平穩信號消噪演算法（ wpm ）已較為成熟，本文將其應用於局部放電在線監測，通過研究其對不同局放波形、采樣率、噪聲水平下的處理效果，首次提出了理想白噪聲條件下提取局部放電信號的曲線，分析了各種因素對該演算法下信號失真的影響。
  4. Allowed the local buckling of elements and made use of the post - buckling strength, the effective width method is often used to calculate the load - carrying capacity

    為了用料經濟，允許板件產生局部失穩，其承載能力以利用板的屈曲后強度為特點的"有效寬度"方法來計算。
  5. For any laminate which exists an obvious deviation between the estimation and experiment of static strength, maximum loads used in fatigue life predictions were obtained by multiplying the maximum loads used in tests with the ratios of analytical strength to test strength, so as to make the calculation feasible

    （ 3 ）將iosipescu剪切強度試驗方法推廣到剪切疲勞，對4準各向同性層壓板試件進行了剪切疲勞試驗。用本文開發的疲勞分析程序預測了被試多向層壓板的剪切強度和疲勞壽命，模擬了局部疲勞失效演變的過程。
  6. In practical application, it is subjected to local plastic strain cycles due to the power fluctuations during reactor operation ; extremely, this power fluctuations could lead fatigue failure

    在反應堆運行過程中，堆功率的波動和水冷卻介質的流動會導致燃料元件包殼局部承受反復的循環變形，極端情況下會導致疲勞失效。
