This article presents a review of recent developments in parametric based acoustic emission
(AE) techniques applied to concrete structures. It recapitulates the significant milestones …

The purpose of this study is to identify the crack initiation and damage stress thresholds of
granite from the Korea atomic energy research institute's Underground Research Tunnel …

Systematical research was implemented to explore the impacts of fiber reinforcement index
V f L f/df (ie, the product of fiber volume V f and fiber aspect ratio L f/df) on the energy …

Recently, the American Association of State Highway and Transportation Officials
implemented a provisional standard that uses thering test'to help quantify a materials' …

Brazilian splitting tests were carried out to study the influence of basalt fiber content on the
acoustic emission (AE) characteristics and crack resistance of concrete. The relationship …

The utility of concrete as a cost-effective, durable structural material depends largely on its
fracture properties. Improved understandings of the physical bases and scaling of concrete …

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 …

An analysis of the Acoustic Emission (AE) activity and of the energy fields is carried out with
reference to three-point bending (TPB) tests on concrete beams with different sizes. First, a …

Different constituents of concrete can have cracking behavior that varies in terms of the
acoustic waveform that is generated. Understanding the waveform may provide insight into …

The aim of this study is to assess damage in the plain concrete using acoustic emission (AE)
energy. During fracturing process of concrete, the AE energy evolves due to the expansion …
