MONITORING BRIDGE COMPONENTS USING ACOUSTIC EMISSIONS

Laboratory investigation into the effectiveness of acoustic emission monitoring as a nondestructive evaluation technique to detect and monitor fatigue cracks in steel bridges indicates some AE instrumentation can readily detect initiation and growth of the cracks in a very noisy test environment. Tests showed a strong, positive correlation existing between the degree of acoustic activity and the rate of crack growth. These tests were performed to evaluate the correlation between AE field test results and laboratory results using accelerated laboratory fatigue testing.
