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 – the 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.
