Abstract
Bared on an analysis of the waveform of the primary acoustic emission signal, the peak value of the acoustic emission signal amplitude is id entified as a parameter that provides direct information about a crack . The dimensions of the crack and the elastic energy density at its or igin are estimated (in direct calibration of the electroacoustic chann el) during the flexure testing of samples in the rest configuration of a beam with built-in ends.
