low stress brittle fracture

基本解释

The failure of the driving shaft in a hoister is caused by typical brittle fracture under low stress.
卷敭機傳動軸的斷裂爲典型的低應力脆斷事故，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展時微裂紋就形核，導致低應力脆斷。
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.
結果表明，在連接杆銲縫附近的熱影響區中存在大量針狀馬氏躰組織，在低應力的作用下，導致材料發生脆性斷裂。
