Summary This paper presents an improved crack model incorporating non‐linearity of flexural damage in concrete to reproduce changes in vibration properties of cracked reinforced concrete beams ...
of the identified resonant frequencies with other monitoring data (temperature, precipitation, crack opening) for the period November 2012 to September 2013 in Fig. 13. Broadly, we identify periods of both direct ...

but increased at a markedly higher rate thereafter. Little change in mesocarp cell volume occurred in a control zone distant from the crack . As water incubation continued, the cell volume in the crack zone ...
) is the transient elastic wave generated by the rapid release of energy within the materials and AE technology has been widely used in investigating rock cracking behaviour(Keshavarz et al.2010; Kim et al.2015 ...
at the micro- and nanoscales. Finally, the effects of the inhomogeneous elastic modulus and surface potential on the EMR from the microscopic perspective were analyzed. In this experiment, the change ...
materials such as rocks, granular material or damaged structures containing cracks exhibit non-classical nonlinear elasticity that originates in the change of material properties at cracks or grain boundaries ...
Compressive Strength (UCS) test, the AET was used to monitor the crack initiation, propagation behaviours during sample deformation (Fig. 5). There are many advances to AE monitor comparing with some ...
the initial crack propagates, the crack initiation of the rock causes the AE signal to produce a sudden mutation change . Mechanical fraction characteristics during rock uniaxial compression after temperature ...
