low stress brittle fracture

基本解釋

The failure of the driving shaft in a hoister is caused by typical brittle fracture under low stress.
卷敭機(jī)傳動(dòng)軸的斷裂爲(wèi)典型的低應(yīng)力脆斷事故，主要原因是傳動(dòng)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(shí)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。
