brittle cracking
解釋
脆性開裂-
: 36 < kth < 37 mpa / m3 / 2, 42 < kih < 44mpa / m3 / 2, 51 < kc < 52 mpa / m3 / 2 through the sem fractography, it is know that the susceptibility to brittle failure at room temperature is more than below 100 ?. and the susceptibility to brittle failure increase with hydrogen increasing, under the sustained loading, ductile cracking appears. the quantity of brittle cracking is more with crack growth
T44mpa m 『 q ， sl lt52mpa in 』 」斷口分析表明，該合金充氫后其室溫時的氫脆敏感性大於100oc時的氫脆敏感性；且隨氫含量升高，氫脆敏感性增加：在恆載荷的作用下，該合金裂二紋開始擴展時顯示的是韌性起裂；隨裂紋增長，試樣脆性斷裂的比例增大。 -
It proves that adding up fiber and modified asphalt in the common asphalt mixture can decrease the brittle point temperature and strength the ability of resisting cracking. fiber - reinforced asphalt concrete and glass fiber grid which has been set between the road base and overlay can delaying reflection cracking effectively
試驗證明，在普通瀝青混合料中加入聚酯纖維以及使用改性瀝青可脆化點溫度降低，增強低溫抗裂性，加入goodroad聚酯纖維和在基層與面層之間鋪設玻纖格柵可有效抑制反射裂縫，值得推廣。 -
It was found that the cracks can penetrate the interphase and the fiber rapidly when the interphase is thin, which causes the low flexural strength and fracture toughness, as well as the composites " brittle fracture. while the interphase is thick, multiple toughening mechanisms such as the crack deflection and matrix cracking can be activated, which cause the composites " flexural strength and fracture toughness is high and the composites " non - brittle fracture
當界面相較薄時，基體裂紋能夠迅速穿過界面相和纖維，復合材料具有較低的彎曲強度和斷裂韌性，表現為脆性斷裂模式；當界面相較厚時，復合材料能產生裂紋偏轉、基體開裂等多種增韌方式，具有較高的彎曲強度和斷裂韌性，呈韌性斷裂模式。 -
In the thesis, the design issues of repairing and strengthening reinforced concrete structure using ferrocement have been provided, and the equations of brittle ratio, cracking load, ultimate load and vertical deflection have been inferred too. at last, a conclusion is shown that the theoretical equations share a good agreement with the experimental results of the tested beams
本文就鋼絲網復合砂漿加固受彎構件的設計進行了探討，提出了界限加強率、開裂荷載、極限荷載以及撓度的計算公式，並將計算公式的結果與試驗結果進行比較，取得了較好的吻合。 -
Abstract : the article analyzes the influence of failure of heat treatment process and equipment for mn13 steel join, and offeres the method of preventing the part slitting and brittle cracking
文摘:分析了熱處理工藝和設備對高錳鋼端頭缺陷的影響，提出了防止高錳鋼端頭脆性開裂的措施。 -
The electrical cut scanning mirror shows : this bilinear behavior results from different cracking ways under high and low strain amplitudes, that is, elastic cracking and brittle cracking respectively. cyclic hysteresis energy is an important fatigue parameter. the total cyclic hysteresis energy of gh4145 / sq increases gradually as strain amplitude goes from 1 % to 0. 5 %, but it decreases when strain amplitude is lower than 0. 5 %
在高溫低周疲勞下， gh4145 / sq合金的循環滯?能具有如下特徵：在1 0 . 5應變幅范圍內，循環總滯?能是一個逐漸增大的過程，而當應變幅小於0 . 5時，總滯?能隨應變幅減小而趨于減小；半壽命處的循環滯迥能和總滯?能與壽命之間的關系曲線表現出雙線性特徵，轉折點對應0 . 5應變幅。
