An experimental study of the effect of back rake angle in rock cutting
Published 2018“…New results on a few rock samples were also obtained by performing novel experimental tests at very large rake angles (θ > 70°) as well as negative rake angles, showing that the intrinsic specific energy increases dramatically once the back rake angle exceeds 75°. …”

Softening of rocks matrix due to water flood: experimental study
Published 2014“…One of themain reasons for this is the physical and chemicalinteractions of carbonate rocks with pore fluids. Suchinteractions can significantly change the elastic propertiesof the rock matrix and grains making the applicability ofGassmann’s fluid substitution procedure debateable. …”
