Overview of moment tensor analysis of acoustic emission signal in evaluation concrete structure

This paper is present a review on the evaluation of concrete structure damage by utilizing the moment tensor analysis (MTA) of acoustic emission (AE) source technique. In general moment tensor analysis is concerning the quantitative information on kinematics of cracks according to the AE source. This concept of AE analysis has been developed and mostly applied in reinforced concrete structure. Furthermore, the formulation of the evaluation of MTA is divided to a three different parts which are; namely kinematics crack, crack classification and crack volume. All these kinds of formulation have been established and proved by the previous researches. This paper also provides a brief overview of research work and several research papers on these topics were cited. Finally, this paper concluded with a discussion for future research area.
