Experimental Analysis on Acoustic Emission of The Fracture Marble Under High Tempreture

Abstract:

Article Preview

The marble acoustic emission characteristics under different temperature tested and analyzed under uniaxial compression, and the contrast analysis that passes to acoustic emission the signal and the mechanics parameters to the marble can get,The characteristic curve of acoustic emission is distinguishing with the variety of temperature and stress level, the acoustic emission characteristic and stress-strain curve of fracture rock exists corelation characteristic. At the same stress-level, along with the temperature raising up, the relevant dimension has the trend of the aggrandizement, and the related coefficient will change randomly. The marble then expresses a mechanics characteristics of soft rock at over 1000oC, and the strength-limit descending sharply. The process parameters of AE count in the time domain has a better self-similar characteristics.
