Abstract
We consider the regularities in the distribution of electromagnetic emission pulses from a sample subjected to stepwise loading upon uniaxial compression, using a multisensory monitoring system. It is shown that electromagnetic emission pulses differ in level, but are close in shape. Therefore, we employ the optimal filtration method for separating the electromagnetic emission pulses from noise. The distributions of pulsed response fluxes are plotted for each loading stage in the log-log coordinates. It is shown that for loads amounting to 60% of the breaking load, a power distribution of electromagnetic pulses is observed. The slope of the straight lines in the plots for the power distribution regularly decreases with the load.
