“…Experiments include pure (isothermal) friction, transient heating experiments or the application of both . Pure friction experiments (Furuichi et al, 2015;Hirono et al, 2015;Kuo et al, 2017;Kirilova et al, 2018;Fan et al, 2020) are performed using a rotary shear apparatus under room temperature conditions, and normal stresses that vary between 1 and 3 MPa (Hirono et al, 2015;, 2.7 and 13 MPa (Ito et al, 2017;Kuo et al, 2017) or 20-60 MPa (Fan et al, 2020) (Table 3).…”
