Investigation on the attenuation trend of Acoustic Emission in reinforced concrete structures

Considered as an effective real-time monitoring tool, Acoustic Emission (AE) measurements is a promising technology for reinforced concrete (RC) structures. However, its application on real RC structures is still limited. Due to the lack of knowledge on the crack induced acoustic emission in large scale structures.<br/><br/>The aim of this study...

Investigation of the Application of adhesively bonded lifting lugs in ship building

Defects are produced when lifting lugs being welded on ship sections during the building process. The large amount of heat produced in the welding work causes “heat affected zone” in the base metal on sections and destroys painted coatings on the plates; and residual stress decreases the mechanical performance of the steel plates. To eliminate...
