Keywords:
non-destructive control, acoustic emission, co-ordinates of defects
Abstract
The mathematical ground of providing of construction of models of determination of co-ordinates of sources of acoustic emission and algorithms of search of defects is offered. It is set that the parameters of signals of acoustic emission are related to local alterations of structure of materials and processes of motion of distributions. Description of structure of model layout of sensors charts is given at control of defects the method of acoustic emission. The formulas of localization of sources of acoustic emission are offered at the different variants of location of sensors on a plane.
