Estimation of Crack Initiation and Propagation Thresholds of Confined Brittle Coal Specimens Based on Energy Dissipation Theory (2017, methodology): “Although the MPRT method reduces subjective judgement, it is especially sensitive to the user-defined regression interval (Eberhardt et al. 1998; Zhao et al. 2015).”
Experimental Study on Damage and Fracture Characteristics of Beishan Granite Subjected to High-temperature Treatment with DIC and AE Techniques (2020, background): “…the mechanical behaviour of rock is known to be dependent on the formation, growth, and eventual interaction of microcracks, the relationship between the microscopic damage caused by thermal treatment and the varied macroscopic mechanical properties of rocks remains poorly understood (Zhao 2015).”
