Abstract

In this work the hardware-software measuring system for registration of acoustic emission (AE) signals based on personal computer (PC) for detection regions of deformation and fracture localization and their location as well as estimation of current mechanical state of loaded materials was designed. Series of experiments on measurement of basic characteristics of AE signals of the D16AT samples with a notch have been carried out under uniaxial tension. The obtained experimental dependences are agreed well with a literature data and interpreted from a position of a stage pattern of the deformation processes occurring under loading.
