Estimation of Crack Initiation and Propagation Thresholds of Confined Brittle Coal Specimens Based on Energy Dissipation Theory (2017, methodology): “New attempts, including moment tensor inversion, b value analysis, AE energy, cumulative AE hits, and AE accumulative counts, have also been applied to determine σci and σcd (Chang and Lee 2004; Zhao et al. 2013, 2015; Kim et al. 2015).”
A Comparative Evaluation of Stress–Strain and Acoustic Emission Methods for Quantitative Damage Assessments of Brittle Rock (2015, methodology): “In this study, a modified methodology to determine crack initiation, crack coalescence, and crack damage thresholds is adopted for a more reliable selection of the stress thresholds, as proposed by Chang and Lee (2004) and Diederichs et al. (2004).”
Strength failure and crack coalescence behavior of brittle sandstone samples containing a single fissure under uniaxial compression (2011, methodology): “As it is well known, Acoustic Emission (AE) technique is an efficient measuring tool to reflect the evolution and propagation of defects in materials, which has been widely applied to investigate the damage and fracture behavior internal the rock material in many past studies (Li et al. 2005; Labuz ”
