Özet

The effects of porosity, unit volume weight and Schmidt hardness on the quasi-static and dynamic compressive behaviors of some carbonate rocks were investigated using classical servo-hydraulic testing machine and split Hopkinson pressure bar (SHPB) testing system, respectively. For dynamic compression testing, cylindrical samples 18 mm in diameter and 11 mm long were obtained from rock samples of light and dark travertines, lymra and beige marbles. For quasi-static compression testing, cylindrical samples were prepared according to the International Society for Rock Mechanics (ISRM) standards. The results of the physical and mechanical properties of the rock samples have shown that the porosity, unit volume weight and Schmidt hardness, have significant effects on the compressive stress-strain behavior of the rock samples under dynamic loading. The results have also shown that the beige limestone samples have significantly higher dynamic compressive strength than the other carbonate rock samples. (C) 2009 Elsevier Ltd. All rights reserved.
