An intelligent sensor system for monitoring fatigue damage in welded steel components

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

A system for monitoring fatigue damage in steel components is described. The sensor, a thin steel sheet with a pre-crack in it, is attached to the component. Its crack length increases by fatigue in service and is recorded using a microcontroller. Measurement is accomplished using conductive tracks in a circuit whose output voltage changes when the crack propagates past a track. Data stored in memory can be remotely downloaded using Bluetooth™ technology to a PC.
