中文拼音 [suìlièzǎihé]
碎裂載荷
英文
crushing load-
Here we obtain the strain compatibility method ande equilibrium of forces and concepts of fracture mechanincs, they can be used to predict the ultimats strength in flexure that can be achieved by such elements, given the cfrp cross - sectional area, or conversely, the required cfrp cross - sectional area to achieve a targeted resisting moment of rehabilitated flexureal elements
Cfrp加固梁在承受彎曲荷載時的破壞是鋼筋屈服后碳纖維斷裂和鋼筋屈服后混凝土壓碎。本文通過應變相容方法和對破壞機理的定義，由給定的cfrp橫截面積預測加固梁的極限彎曲強度；或者相反，在已知加固梁的極限彎曲強度時可以求出所需的cfrp橫截面積。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。In numerical simulation, the elastic zone is only considered and the effect of blasting waves on the rock medium, after attenuating through crushing zone and ruptured zone, becomes an input load
數值模擬僅考慮彈性區域，爆炸波對巖石介質的作用經粉碎區、破裂區衰減后成為輸入荷載。The roof supporting object ( or the loading source ) is the hulking deformation ( or the hulking force ) produced during the enlarging of a broken state zone after erecting a support
破裂區發展產生的碎脹變形或碎脹力是地下工程支護的對象或載荷來源。Here aiming at temperature and traffic load factors, have a systemic study about strcture ' s stress distribution. plan is to make use of ansys to calculate pavement structure ' s distortion with full grade gravelly interlayer carefully through changing each layer ' s thickness and module. next, analysize stress among bottom of surface asphalt layer and top of semi - rigitidy base. lastly. make a conclusion : how to distrube stress and strain about the structure after adding gravelly interlayer
方法是採用ansys對加設級配碎石基層半剛路面結構進行多種參數模擬計算，通過改變結構材料厚度、模量等觀察基層和面層應力變化，研究碎石基層怎樣調整結構應力而防止了溫度和行車荷載產生的過大拉應力，避免基層產生內部裂縫。It is found that the great cracks on the coarse surface are initiated easily than on the smooth surface by the sem observation and the crack size obtained at the dynamic indentation experiment is bigger than at the static indentation experiment under the same load. it is showed the single crystal silicon is easier to initiate the crack and fracture under dynamic load, the single crystal silicon ’ s
然後通過sem觀察單晶硅試件表面壓痕形貌，發現粗糙表面比光滑表面容易生成大裂紋，在相同載荷作用下單晶硅材料在動態壓痕試驗得到的裂紋要大於在靜態壓痕試驗得到的裂紋，表明在動態加載條件下單晶硅材料更容易生成裂紋和破碎。分享友人
