dc.description.abstract Acoustic emission (AE) technique is widely used for studying deformation and fracture behaviour of materials. An acoustic emission is the elastic energy that is spontaneously released by materials when they undergo deformation. In this study, an attempt has been made to investigate the AE signal generated during tensile test of mild steel plate (ASTM A-370 standard) with 6 mm thickness at room temperature, after that the generated AE signal was compared to the conventional tensile result to get their correlation. AE monitoring was carried out using AE sensor by placing directly on the shoulder of the specimens. The AE signal output from the sensor recorded for every second using the computer system with the LabView TM software. The result shows that the AE signal generated from all specimens is rapidly increases in the elastic region. Meanwhile, in the yield region AE signal shows the maximum value and after that AE signal decreased exponentially with the plastic deformation. Then, the generated of AE signal is low and achieved nearly the ultimate strength and after that it was low or nearly zero. It is concluded that the initial of plasticity, particularly at or n ear the yield stress contribute to the highest level of AE observed on a tensile curve. en_US
