A Comparative Evaluation of Stress–Strain and Acoustic Emission Methods for Quantitative Damage Assessments of Brittle Rock (2015, methodology): “00 or less as macro-cracks form and the material approaches failure (Rao and Lakshmi 2005; Cox and Meredith 1993; Hatton et al. 1993; Colombo et al. 2003).”
Stress Drop and Stress Redistribution in Concrete Quantified Over Time by the b-value Analysis (2006, methodology): “[7] showed that the number of events belonging to each group has to be verified because this parameter can influence the results.”
Influence of damage in the acoustic emission parameters (2013, background): “magnitude diagram and hence it represents the slope of the amplitude distributions [4,33,34].”
A review of recent developments in parametric based acoustic emission techniques applied to concrete structures (2012, methodology): “[21] concluded that the larger b-value indicates the states of damage in concrete structure in which microscopic cracks occur more predominantly and the smaller b-value indicates the occurrence of macrocracking as shown in Figure 2.”
Damage classification in reinforced concrete beam by acoustic emission signal analysis (2013, methodology): “RA analysis and b-value methods have also been used to analyse post-test AE signals for crack classification [5,14,15].”
From criticality to final collapse: Evolution of the ''b-value" from 1.5 to 1.0 (2009, background): “It also seems that the minimum theoretical value for b could be one [1,2], although this is still an open issue.”
The influence of thermal-stressing (up to 1000 °C) on the physical, mechanical, and chemical properties of siliceous-aggregate, high-strength concrete (2013, methodology): “It has been suggested that the monitoring of b-values could be used as a method for tracking progressive damage in concrete bridges [92].”
