Abstract
The present disclosure relates to a discrete element method (DEM)-based simulation method and system for acoustic emission (AE). The simulation method includes: arranging a monitoring point on a surface of a numerical model; monitoring a velocity waveform of the monitoring point; and analyzing the velocity waveform to obtain a hit, energy, and a b-value of AE. The method in the present disclosure can resolve problems of principle incompliance, poor authenticity, and high occupation of calculation resources in a traditional simulation method for AE.
