METHOD FOR ASSESSMENT OF STRUCTURE DESTRUCTION PROCESSES IN ACOUSTIC-EMISSION CONTROL Russian patent published in 2009 - IPC G01N29/14 

FIELD: physics, tests.

SUBSTANCE: application: for nondestructive check of structures. Assessment of destruction processes in case of structure deformation is carried out by means of analysis time breakdown into fixed intervals, number of emission acts is measured on each of these intervals, average values of acts number and their squares are assessed by time of analysis, and then expectation value of random variable square, which is the average number of acoustic emission acts, in divided into sum of square of expectation value of this random variable and actually this random variable expectation value, and deviation of quotient from zero is used to detect availability of developing damage processes.

EFFECT: provision of efficient and more valid assessment of damage accumulation and structure damage process assessment during periodical and permanent acoustic-emission control.
