Structural Health Monitoring with Smart NDE Technology

摘要

Smart NDE(Nondestructive Evaluation)technology deals with advanced sensing technology having small size,real time operation,and non-contact measurement rising the conventional NDE technology such as ultrasonic test,acoustic emission,visual test etc.This technology can also apply on structural health monitoring.Safety metrology group of KRISS is working on NDE technology during about 25 years.In this presentation,we are going to briefly introduce our works about smart NDE technology for structural health monitoring.At first,we explain some sensing technology based on ultrasonic test implemented by advanced MEMS based transducer and phased array EMAT(electromagnetic acoustic transducer).Also,laser based ultrasonic test is included.Secondly,we move to watch on some works of smart active layer technology to detect acoustic emission signals of structural damages.Lastly,we carry on fiber optic sensor technology,which measure some distributed displacement and temperature on the surface of a building.
