The possibility to combine the use of acoustic emission and thermal emission as real-time monitoring techniques on carbon-epoxy composites is the subject of this paper. Tensile tests are therefore performed, using a cross-head speed not too high so to enable a reliable detection of acoustic emission signals, but suitable also for the needs of the thermal emission technique,. The latter techniqu...

this paper deals with an inspection of defects including corrosion and leakage by acoustic emission (ae) in an oil tank floor. in contrast to intrusive methods such as magnetic flux leakage, eddy current or ultrasonic, there is no need to emptying and entering the tank in ae method in order to inspection. in this research ae investigation and ae source location is presented in detail. the resul...

The fundamentals associated with acoustic emission monitoring of fatigue crack initiation and propagation of Ti-6AI-4V were studied. Acoustic emission can detect and locate incipient fatigue crack extensions of approximately 1 0 gm. The technique therefore can serve as a sensitive warning to material failure. There are three distinct stages during which acoustic emission is generated. These sta...

A study of acoustic emission technique for concrete damage detection", Master's report,

One of promising possibilities of watching of damage course of material exposed to cyclic mechanical loading is using acoustic emission technique (AE). In the signal monitored on the surface of material, it is possible to identify course of a number of processes that appear both on the surface and inside the material of the construction. From this point of view, we can see that this method coul...
