Research on Relationship Between Parameters Correlation of Acoustic Emission and Rock Failure

Analyzes that granite AE signal parameters under uniaxial loading by that way of Pearson linear correlation, research that correlation of characterization parameters within that separate group with various characteristics, and analyzes that relationship between each parameter and destruction. This study shows that: impact, events and ringing are mainly used to describe the damage degree of rock...

Fractal and Chaos Characteristics of Acoustic Emission During Failure of Cemented Filling Body

The cemented filling body is taken as the object of this study, whose nonlinear dynamic characteristics of damage and instability are researched by virtue of acoustic emission (AE) under uniaxial cyclic loading and unloading test. The results show that there exists similarity in variation trend between correlation dimension and maximum Lyapunov exponent during each loading stage, which also ver...

Study 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...

Acoustic Emission during Stress Corrosion Cracking Test

AE monitoring from various types of stress corrosion cracking (SCC) has been conducted for the past 15 years in our laboratory. This paper discusses AE results of active-path dissolution-type SCC of austenitic stainless steel in chloride solution and fused salt, fluoride and polythionic acid solutions, brass in ammonia (Mattosson's solution), and carbon steels in nitrite solution. Transgranular...
