- The working principle of the AE sensor is introduces,and the AE testing system of grooving sample fracture under cyclic load is set up.
- On the basis of the structural characteristics of a single ram BOP, a scheme of planar location of AE test is proposed.
- Acoustic emission (AE) characteristics of a sandstone sample in fatigue failure process were analyzed by AE testing and its fatigue damage evolution rule was studied.
- According to AE testing data of more than 500 pressure vessels, the characteristics of acoustic emission sources are listed and analyzed which could be encountered during field pressure vessel test.
