Non-Destructive Method of Determining Rock Strength

Authors: Robert J. Allison, University of Durham, Department of Geography

Abstract

Rock material strength is an important componet of many geomorphological studies. Current methods for determining this parameter result in sample destruction, preventing further analysis. A new non-destructive technique is described for indirectly determining material strength, by measuring Dynamic Young’s Modulus. Tests have been conducted on Jurassic Portland Limestone and Upper Cretacious Chalk to assess the apparatus. Young’s Modulus is becoming an increasingly important rock material property.
