Acoustic Emission in Materials Research – a Review
This paper reviews progress in methods of signal analysis used in acoustic emission (AE) as applied to materials research field. The achievement and inadequacy in understanding of AE from materials during the deformation, fracture and other processes are examined systematically. New goals for the future are also discussed in view of new analytical tools and vastly advanced instrumentation.
متن کاملCluster Analysis of Acoustic Emission Signals for Carbon/Epoxy Composite in Four-point Bending Test (RESEARCH NOTE)
Due to the extensive use of composites in various industries and the fact that defects reduce ultimate strength and efficiency during operation, detection of failures in composite parts is very important. The aim of this paper is to use Acoustic Emission (AE) non-destructive method in four-point bending test of carbon/epoxy composite to analyze and examine the failure mechanisms. This method is...
متن کاملOn the Use of Acoustic Emission and Digital Image Correlation for Welded Joints Damage Characterization
A series of tests have been conducted to investigate fatigue damage characterization in corroded welded steel plates using structural health monitoring (SHM) techniques. Acoustic Emission (AE) is a non-destructive testing (NDT) technique with potential applications for locating and monitoring fatigue cracks in service. In the present work, AE is implemented to characterize damage during crack e...
متن کاملStudy of the Frictional Surface Damage Using Acoustic Emission Method
In this study, the change at rubbing surfaces has been investigated experimentally using an acoustic emission signal monitoring system. A steel ring is slipped on the surface of a metallic sheet to simulate frictional conditions. The mechanical disturbances caused by the movement of the ring produce stress waves propagating along the sheet surface. The out of plane displacement of the sheet su...
متن کاملPulsed Magneto-acoustic Emission Sensor Array for Stress Measurement and Material Characterisation
This paper introduces a new method of pulsed magnetic acoustic emission (MAE) for stress detection and material characterisation and investigates the viability of implementing an acoustic emission sensor array for enhanced location information and noise suppression. Pulsed excitation can provide wide spectral components for non-destructive evaluation and material characterisation and lead to gr...
