It can be seen from the results that the control beam had good plastic property in the static failure experiment after two million fatigue loading circles. all specimens with corroded main bars were failure under the fatigue loads within one million fatigue circles. fatigue lifespan of reinforced concrete beam was sharply shortened after main bars corroded in it and the beam was destroyed bristly without any prediction
試驗結果表明,振動測試不能夠對銹蝕鋼筋混凝土梁的疲勞破壞做出可靠的預測;對比梁在經過200萬次疲勞循環加載后的靜力試驗中仍表現出良好的延性破壞特徵;銹蝕梁在100萬次疲勞循環內均因主筋疲勞斷裂而破壞;主筋銹蝕使得梁的疲勞壽命急劇縮短;梁發生脆性破壞而沒有徵兆。In the first part of this dissertation, theory of fracture mechanics of the frozen soil has been presented. a general strength theory based on fracture mechanics was proposed, and the validity of the theory using in frozen soil was discussed. the fracture toughness values for different kinds of cracks extension were determined, such as the plane strain fracture toughness for mode i cracking ( kic ), fracture toughness for mode cracking of frozen soil and the intersection of frozen soil and concrete
論文第二章為凍土斷裂力學的基本理論,包括斷裂力學在凍土研究中的工程適用性、條件適用性、平面應變斷裂韌度測試的適用條件等,給出了凍土斷裂韌度k _ ( c ) 、 k _ ( c ) 、 -型復合斷裂測試的基本原理及試驗方法,並基於weibull脆性破壞理論推導了凍土三點彎曲試樣k _ ( c )尺寸效應系數,為後面的工作提供理論基礎。With the decreasing of heterogeneity, the main failure process presents brittle behavior, and vice versa, with the increasing of heterogeneity, failure process presents ductile behavior
隨著非均勻程度的降低,主破裂呈現脆斷模式,而隨著非均勻程度的增加而呈現韌性破壞特徵。In order to verify these criterions, tensile experiments are carried out for many kinds of samples made out of plexiglas with a planar v - notch under mixed - mode of i and ii
為了檢驗上述脆性斷裂準則,用脆性材料pmma加工成多種型、 -復合型v型切口試樣,進行了拉伸破壞實驗。But calcium phosphate ceramic with high porosity is such brittle and low toughness that it ca n ' t fit to bone tissue engineering. in order to provide appropriate scaffolds for bone tissue engineering, calcium phosphate was combined with plla to prepare porous material
但磷酸鈣多孔陶瓷材料脆性大,在生理環境中的疲勞與破壞強度不高,尤其在濕環境下斷裂韌性很低,不能制得滿足組織工程要求的高孔隙率,力學性能較高的支架材料。The cohesive theory has proved effective in the simulation of complex fracture processes including : the fragmentation of brittle materials ; dynamic fracture and fragmentation of ductile materials ; and the dynamic brazilian test for concrete
已證實此理論對復雜的斷裂過程的模擬是有效的,包括:脆性材料的斷裂、韌性材料的動態斷裂和破碎、混凝土的動態bazilian測試等等。Further, the mechanical behavior and fracture features under flexural load of the c / sic composites are discussed with mechanical properties contract to microstructure and cvi - pip process parameters. the multiple fracture phenomenon of the c / sic with high toughness connected to multiple interface fracture is found, which supplements the conventional composite theory on the relationship between strength and fracture mode
聯系化學組成及微結構參數、工藝參數,進而研究了彎曲載荷下該c / sic復合材料的行為特徵和失效過程,發現了一種與多重界面失效緊密聯系的、高斷裂韌性的多重損傷累積型材料破壞現象,補充了傳統的脆性基體復合材料強度一斷裂韌性理論。分享友人
