Sclerograph Measurements on Rock Materials

CODEN: GTJODJ

Abstract

Theoretical analysis of the sclerograph test for rock materials shows that a considerable and unknown amount of the sclerograph piston's impact energy is converted to internal vibration in the piston after impact. Nevertheless experimental results show that the piston recoil factor κ correlates remarkably well with other, more easily understandable rock strength data, such as the tensile strength index #x03C3;PLT obtained from the point load test; σPLT ⋍ σPLT* exp (4κ) where σPLT* ⋍ 1.0 MPa.
