Influence of cylindrical specimens height on tensile strength of oil shales
Authors:
Abstract
In determining the strength of rocks, a scale effect or scale factor-dependence of test results on the size of samples has been found. Experimental studies of the manifestation of this phenomenon lead to contradictory results, and some authors generally deny its existence.
