摘要
对具有人工缺口的高强度钢瓶进行疲劳试验研究,试验结果表明,人工缺口在高强度钢瓶疲劳试验过程中,并不以整个缺口作为疲劳裂纹扩展,新的疲劳裂纹在人工缺口的夹杂处萌生和扩展,引起钢瓶失效。
It is investigated that high strength strength steel flawde cylinder was cycled. It was showed that the flaw doe~ not propagate as a whole crack during the pressure cycling test and new fatigue cracks will originate in the flaw and lead to the tested flawed cylinder to leak.
