Acoustic emission monitoring is widely used for damage detection in materials research and
for site monitoring. Its use for masonry structures is however challenging due to the highly …

The utilization of deep mineral resources is severely restricted by dynamic disasters, such as
rock burst, caused by mining disturbances. This study is aimed at investigating the instability …

In recent years, microwave mechanical rock breaking—an energy-saving technology with
environmental benefits and high efficiency—is increasingly being used to improve the rock …

Notched three point bend (TPB) specimens made with plain concrete and cement mortar
were tested under crack mouth opening displacement (CMOD) control at a rate of 0.0004 …

Acoustic emission (AE) is a vital analysis method used to explain the fracture properties of
concrete specimens. Four representative analyses methods, including the b-value method …

Several materials of technological interest could be considered as heterogeneous and their
random nature can be accounted to be the cause of the nonlinear behavior. The quantitative …

Understanding the mechanical behaviour of rock under heating and cooling cycle condition
is necessary for safe and effective deep geo-engineering applications, including geothermal …

Rockburst poses a great threat to the construction safety of deep tunnels under high
geostress conditions. Recently, numerous deeply buried tunnels have been constructed in …

Acoustic emission (AE) is a Non Destructive Inspection Technique, widely used for
monitoring of structural condition of different materials like concrete, masonry and rock. It …

A micro-cracking monitoring and fracture evaluation method for crumb rubber concrete
based on the acoustic emission technique was developed. The precursory micro-cracking …
