  1. According to the recorded full process fracture curve, the paper calculated and compared the fracture toughness ( kic ), the fracture energy ( gf ) and crack tip opening displacement ( ctod ) of the different strength grade boulder concrete and crushed stone concrete, it is found that the maximal load ( fmax ) and the fracture toughness ( kic ) of boulder concrete and crushed stone concrete increase when the strength of them increases, so does the fracture energy of boulder concrete, but the fracture energy of crushed stone concrete does n ' t obviously increase when it ' s strength increases. the crack tip opening displacement ( ctod ) of all specimens chang less when the strength of concrete increases, so it is concluded that the location of the axle in the ligament of the specimens is relatively stable

    根據記錄的全曲線,計算了不同強度等級的卵石混凝土、碎石混凝土的斷裂韌度k _ ( ic ) 、斷裂能g _ f以及裂縫的尖端開口位移ctod ,比較了不同強度等級卵石混凝土及碎石混凝土的斷裂韌度k _ ( ic ) 、斷裂能g _ f以及裂縫的尖端開口位移ctod的關系,發現卵石混凝土、碎石混凝土的荷載峰值fmax 、斷裂韌度k _ ( ic )隨強度增加而增加,卵石混凝土的斷裂能g _ f隨強度增加而呈增加趨勢,碎石混凝土的斷裂能g _ f隨強度增加變化趨勢平直,增勢不明顯。

  10. The strain energy release rates g near crack tip under different conditions were calculated by employing three methods of the fracture mechanics ( j - integral, straightforward method and crack tip opening displacement method )

    並在有限元模擬中採用三種不同的斷裂力學方法(裂縫頂端開口位移方法、直接方法、 j積分方法)計算了焊點斷裂與否時的能量釋放率g 。
  11. By comparing the fracture toughness ( kic ), the fracture energy ( gf ) and the crack tip opening displacement ( ctod ) of the same strength grade concrete, it is found that the values of the fracture toughness ( kic ), the fracture energy ( gf ) and the crack tip opening displacement ( ctod ), tested by three - point - bending method and wedge - split tensile method approach, so it is proved that the fracture toughness ( kic ), the fracture energy ( gf ) and the crack tip opening displacement ( ctod ) are related to its own properties such as material, specimen size, and crack size, but unrelated to the test - method

    通過比較三點彎曲法和楔入劈拉法測定的相同強度等級混凝土的斷裂韌度k _ ( ic ) 、斷裂能g _ f以及裂縫的尖端開口位移ctod ,發現兩種試驗方法測定的斷裂韌度k _ ( ic )斷裂能g _ f以及裂縫的尖端開口位移ctod的數值接近,從而證明混凝土斷裂韌度、斷裂能、 ctod的值僅與材料、試件尺寸、裂縫尺寸等試件自身的性質有關,而與試驗方法無關。
