Analysis of Precursors Prior to Rock Burst in Granite Tunnel Using Acoustic Emission and Far Infrared Monitoring

Flexural 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...

Characteristics 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 ...

Pitting Corrosion Monitoring Using Acoustic Emission

Statistical properties of dust far-infrared emission

Context. Far-infrared dust emission has a self-similar structure which reveals the complex dynamical processes that shape the interstellar medium. The description of the statistical properties of this emission gives important constraints on the physics of the interstellar medium but it is also a useful way to estimate the contamination of diffuse interstellar emission in the cases where it is c...
