“…In real terms, measured rates of warming (always less than 0.2°C/min) are an order of magnitude below typicallyquoted thresholds for thermal shock (Δ2°C/min, Hall and Thorn, 2014;Richter and Simmons, 1974). This reflects the temperate summertime conditions simulated here (18°C to 29°C over a 6-hour period).…”

“…Because this data set enables the determination of spatial and temporal variability of the temperature characteristics of the rock over an entire year, this surface temperature data set is an unprecedented opportunity to address the frequency, duration and/or magnitude of conditions that are often hypothesized to lead to fracture. Hypotheses related to processes such as freeze-thaw (e.g., the amount of time a rock is in the proposed −4 to −15 • C range thought to be ideal for fracturing by sustained freezing temperatures; Walder and Hallet, 1985;Hallet et al, 1991) and/or thermal shock (e.g., the hypothesized 2 • C min −1 threshold often cited for thermal shock fracturing; Richter and Simmons, 1974) can be directly tested with the data set.…”

“…Meanwhile, brittle transcrystalline fracture morphology represented by cleavage fractures and transcrystalline cracks existed in the sandstone fracture at the lower hating rate (Figure 12(a)). At the heating rate of [20][21][22][23][24][25][26][27][28][29][30] ∘ C/min, there were two kinds of brittle fracture morphology (transcrystalline cracks and intergranular cracks) in the sandstone fracture after the impact tensile damage (Figure 12(b)). At the heating rates of 40-50 ∘ C/min, tearing ridges became the key fracture morphology, and transcrystalline cracks occurred locally and propagated gradually (Figure 12(c)).…”

“…Thirumalai and Demou [25] tested granite at different heating rates (5 ∘ C/min, 20 ∘ C/min, and 50 ∘ C/min) in heat treatments of 20-400 ∘ C and found that, at the same temperatures, the effects of heat gradually increased as the heating rate increased. By heating gabbro to 300 ∘ C at heating rates of 5 ∘ C/min and 1 ∘ C/min, Richter and Simmons [26] found that thermal expansion differed by 10 percent between the two heating rates, and the fracture characteristics of the sandstone were more remarkable at the faster heating rate. In metal material engineering, heating rate is the key factor in changing the mechanical properties of materials because it not only significantly affects crystal texture and recombination but also further influences the macroscopic mechanical properties [27][28][29][30].…”
