- Effects of Thermal Treatment on Tensile Strength of Laurentian Granite Using Brazilian Test (2015, background): “Beyond 100 C, there is a sharp decrease in the P-wave velocity, which can be explained by the increase in both number and width of the thermally induced microcracks with the heating temperature (Nasseri et al. 2007).”
- Thermal damage pattern and thresholds of granite (2015, background): “Analysis of mineral–mineral contact types along the test fracture path in thermally treated granite specimens showed that pre-existing thermal damage mainly around grain boundaries leads to a larger volume of rock affected by fracture propagation (Fredrich and Wong 1986; Nasseri et al. 2007).”
