Acoustic Emission Response and Damage Process for Q235 Steel in an in Situ Tensile Test
نویسندگان
چکیده
Q235 steel is widely used in engineering and construction. Therefore, it important to identify the damage mechanism acoustic emission (AE) response of material ensure safety structures. In this study, an AE monitor system situ tensile test with optical microscope were investigate insight into process steel. The surface specimen was polished etched before order improve quality micrographs. Two kinds responses, namely a burst continuous signal, recorded by during test. Based on test, observed that induced crystal slip inclusion fracture. Since ongoing process, signals produced, while possibly produced fracture which occurred suddenly released higher energy. addition, great number high amplitude yielding stage then decreased.

In order to investigate the approach to characterize the damage behavior of ferromagnetic material components with flaw by metal magnetic memory testing, a sheet specimen with a precut notch of Q235 steel was chosen to measure the self-emitting magnetic signals on its surface during tensile test. The results showed that an abnormal magnetic signal appeared at the position of the precut notch af...

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...
