    Ultrasonic pulse velocity as a way of improving

    Uniaxial compressive strength tests were performed according to standard test EN 1926 2007 using an Ibertest MEH-2000HFIB-50 servo-controlled hydraulic testing frame. Six samples of each lithotype were tested. Uniaxial compression test was performed at a constant displacement rate of 4 mmh.

    Compressive Strength of Diamond from First

    Compressive strength, like tensile and shear strength, is one of the intrinsic mechanical properties of solid materials. We investigated the ideal compressive strength and corresponding compressive deformation of diamond using pseudopotential density functional theory. The calculated uniaxial compressive strength of diamond is 223.1, 469.0, and 470.4 GPa along the 100 , 110 ,

    In previous statistical studies on igneous hard rocks, the correlation of uniaxial compressive strength UCS values in different diameters with estimations of specimen size effect models was weak. In view of this knowledge gap, the present research proposed a model of appropriate size effect in igneous hard rocks.
