Determination of nanocharacteristics of strength of structural materials based on signal recording and simulation of time dependences of acoustic emission parameters

Non-destructive testing of the strength of structural materials and products from them is currently based on the correlation between the strength characteristics of the material in a real object and the results of laboratory tests of the strength of standard macro samples. The strength properties and conditions of control's heterogeneity of different material's zones of a complex real object make this correlation ambiguous, introducing uncertainty in the results of control. The solution of the problem is connected with the necessity of information transfer to the micro-and nano-level control that determines the strength, the universal physical nanoconstants and the applying of representative micro structural elements of the material as reference. The selection's principles of these elements and the method of assessing their strength characteristics are considered on the basis of information filtering the results of recording acoustic emission signals (AE) and the micro mechanical model of its parameters.
