Research of Acoustic Emission Characteristics at Fracturing of Porous Iron

Amplitude distributions and Fourier spectrums of acoustic emission signal for fracturing porous iron were obtained. The influence of porous structure reorganization for porosities near the percolation threshold on these characteristics was showed.

Keywords: аcoustic emission, porous iron, amplitude distribution, spectral characteristics, fracture, percolation transition.
