Abstract
Acoustic emission energy is one of the important characteristic parameters in AE signals. AE energy can reflect the deformation mechanism of materials, AE energy history analysis method can evaluate the activity and development trend of AE sources, AE energy distribution analysis method can be used to evaluate the intensity of AE sources, and AE energy history analysis method and AE energy history analysis method can be used to evaluate the intensity of AE sources The acoustic emission energy distribution analysis method combines the energy, cumulative energy and the change of applied external load with the arrival time, which is used to reflect the basic characteristics of different stages of the acoustic emission signal generated by concrete after external load, so as to realize the recognition of the acoustic emission signal of concrete.
