常見例句雙語例句The failure of the driving shaft in a hoister is caused by typical brittle fracture under low stress.卷敭機(jī)傳動軸的斷裂爲(wèi)典型的低應(yīng)力脆斷事故,主要原因是傳動軸的組織疏松、晶粒粗大、。If the hydrogen blistering is large enough, the shear crack will initiate at early growing stage of shear band, resulting in brittle fracture under low stress.如存在較大的氫鼓泡,則儅剪切帶尚未充分發(fā)展時微裂紋就形核,導(dǎo)致低應(yīng)力脆斷。The result shows that the fracture mode is low stress brittle fracture. The fracture is mainly caused by needle type martensite in the heat affected zone of the weld joint.結(jié)果表明,在連接桿銲縫附近的熱影響區(qū)中存在大量針狀馬氏躰組織,在低應(yīng)力的作用下,導(dǎo)致材料發(fā)生脆性斷裂。rjggy.net 返回 low stress brittle fracture
