• Damage quantification of intact rocks using acoustic emission energies recorded during uniaxial compression test and discrete element modeling (2015, background): “In practice, AE events have been observed as early as the crack initiation strength (~40-60% of the peak strength) is reached [Cai et al., 2007; Cai, 2010].”
• Numerical modelling of magma dynamics coupled to tectonic deformation of lithosphere and crust (2013, background): “C is the cohesion, ϕ the friction angle and σT = C/R the tensile strength of the host rock with 2 ≤ R ≤ 8 a parameter specifying the reduction of strength of the host rock under tensile stress (Cai 2010).”
• A Comparative Evaluation of Stress–Strain and Acoustic Emission Methods for Quantitative Damage Assessments of Brittle Rock (2015, background): “Martin (1993), Martin et al. (2001) and Cai (2010) noted that the peak strength (rc) of granite is not a unique material property but instead depends on the geometry of the specimen, the loading rate, and the testing environment.”
• A Review of the Tensile Strength of Rock: Concepts and Testing (2014, neutral): “…– Perras et al. (2013a) Meta-pegmatite – 11.5 (19) 217.4 (14) 103.3 (14) 166.5 (12) Jacobsson (2005, 2006), Cai (2010) Peridotite – 7.3 (4) 111.0 (2) 61.0 (2) – Cai (2010) Quartzite 16.3 (2) 13.0 (3) 172.0 (3) 78.0 (2) – Courtesy of Evert Hoek Cai (2010), Ramana and Sarma (1987) Sandstone…”
• Objective Determination of Crack Initiation Stress of Brittle Rocks Under Compression Using AE Measurement (2015, methodology): “It should be noted that although AE monitoring can be used as an alternative tool to determine rCI, a clear boundary between background noise and true crack initiation can be difficult to determine (Cai 2010).”
