System for detecting surface defects in materials of engineering structures

Abstract

System for detecting surface defects in materials of engineering structures

Isaeva A.S., Denisenko M.A.

Incoming article date: 08.06.2020

The article describes the implementation methodology, structure and functional diagram of a surface defect detection system based on the method of electrical impedance tomography in materials of engineering structures that are subjected to significant loads during operation. A control device for the system for collecting measurements and supplying voltage to the boundary electrodes of the sensing element is considered and an algorithm for its operation is described. The implementation method is proposed and the simulation results of this system are presented.

Keywords: defect monitoring, non-destructive testing, electrical impedance tomography, modeling, sensitive element, functional diagram
