Fractal Stick-Slip Processes and Acoustic Emission Spectra for Analysis of Mode I Fracture in Fibrous Cementitious Composites

Abstract

AbstractThis study presents fast Fourier transform (FFT) based spectral analysis of acoustic emission (AE) waveforms to assess damage and fractal stick-slip processes in fiber reinforced composites. Mode I fracture experiments were conducted on plain ...Practical ApplicationsDistributed microcracking is one of the most challenging forms of damage to detect because it often involves minute changes in the structure that are not immediately detectable. This study enhances the real-time nondestructive ...
