Magnetic Sensor for Nondestructive Evaluation of Deteriorated Prestressing Strand Phase II

摘要

This report gives an account of the execution and achievements. in Phase II of the project completed throught Auguest 2001. The Main objective of this project is to advance the practical development of a nondestructive testing and evaluaion method using and magnetic field technique to estimate corrosion in prestressing strands. The importance of developing such a method has been well establihsed. Phase I and the literature review establihsed the proof of concept for a magnetic inspection method. The magnetic technique of induced magnet field(IMF) was developed.
