In this Paper, UCS of limestone rock was determined by indentation testing on rock fragments. The size of the fragments was in the range of 2 to 5 mm, which is within the size range of drill cuttings. Here, scatter of the data was investigated by calculating the coefficient of variation that...

Indentation testing has been developed as an unconventional method to determine intact rock strength using small rock specimens within the size of drill cuttings. In previous investigations involving indentation testing, researchers have used different indenter stylus geometries, penetration...

Size DependencyIn this study, uniaxial compressive strength (UCS) of limestone rocks was estimated by indentation testing on small rock fragments. Here, the effects of rock fragment dimensions (particularly area and thickness) on indentation indices were studied. The investigation shows size...
