Abstract
The objective of this paper is to model acoustic emission (AE) sources and examine the propagation characteristics of AE waveforms generated by these sources in—concrete structures using finite element (FE) simulation. In order to model AE sources in the form of tensile and shear cracks, a new simulation technique is developed, where the sudden release of nodes is introduced at the crack face on a stressed concrete FE model. In this context, two different concrete models are used for the study, namely the concrete half-space model and the concrete beam model. The resulting AE waveforms are analysed using the wave speed and scalogram to classify various types of AE sources. It is shown that due to a tensile crack at the surface, S-waves and surface (or Rayleigh) waves are formed, whereas, a shear crack at the surface, predominantly produces S-waves. On the other hand, body waves (P- and S- waves) are predominantly formed for internal tensile as well as shear cracks. The developed simulation technique and signal processing tools are expected to be helpful for the direct correlation of AE waveforms with the recorded signal and identification of various AE sources in an experiment.
