Experimental studies of sliding friction and wear via acoustic emission signal analysis

Online monitoring of acoustic emission for quality control in drilling of polymeric composites

“…Jiaa and Dornfled [8] examined the use of acoustic emission for detecting delamination of composite laminates during drilling. Their results showed a linear energy level increase in AE based on the size of entry and exit hole in the composite.…”

Monitoring of Ultraprecision Machining Processes

“…Jiaa and Dornfeld [38] investigated the friction and wear behaviour of metals in sliding contact using AE-signal analysis techniques, it was determined that three different regions (running-in, steady state, and self-acceleration) in long-sliding distance tests can be distinguished from the results of AE rms signal and measured wear rate.…”

The relationship between acoustic emissions and wear particles for repeated dry rubbing

“…The effectiveness of AE in recognizing and quantifying transient phenomena (e.g., the detection of failure of a lubricant [6], the prediction of seizure [7], and the detection of cracks in bearings [8]) has already been identified. Also, several investigations have demonstrated a correlation between AE signals and tribological characteristics [9][10][11][12]. However, little is known regarding the relationship between AE and tribological phenomena, because of the complexity of such phenomena.…”
