Characteristics of Acoustic Emission Signals from Composites
Certain characteristics of acoustic emission (AE) signals from graphite-epoxy composite specimens were correlated last year with the mechanical behavior of the materials. Moisture degradation, which reduced the ultimate strength, resulted in a change in the AE amplitude distribution early in the loading history. Also, AE having distinct frequency spectral types tended to occur at or near singul...
متن کاملThe click-evoked oto-acoustic emission, c-EOAE, in preterm-born infants in the post conceptional age range between 30 and 68 weeks.
Click-evoked otoacoustic emissions (cEOAEs) were repeatedly recorded in an operational sample of 144 very low birth weight (VLBW) infants. A subgroup of 22 was composed of all those babies in which at least 4 recordings were successfully done. The mean birth weight of this group was 1040 g, and the mean duration of assisted ventilation was 17 days. The OAE-recordings were done in the post conce...
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 کاملCharacteristics of acoustic emission during single diamond scratching of granite
The acoustic emission (AE) measured during single diamond scratching of granite can provide valuable information about the structural composition and sawability of natural stone material. As described by Prof. Dr.-Ing. R. Clausen*, Dr, C.Y. Wang** and Dr,-Ing, M. Meding***, scratching tests are shown to i ndicate a direct relationship between the characteristics of AE generated by scoring, the ...
متن کاملFlexural monitoring of carbon fiber/epoxy composite by acoustic emission
Carbon / epoxy composite is one of the most useful polymer matrix composites that has special properties such as high strength-to-weight ratio, high hardness, high corrosion resistance, Resistance to nuclear radiation has high consumption in different industries such as aerospace industry. Therefor monitoring of loading of this type of composite is important. In order to determine failure mecha...
