Abstract
A new application of the basic griffith theory of rupture of brittle solids, based on direct measurement of fracture energy requirements, is presented. The energy balance hypothesis is demonstrated by direct experiment, and nonrecoverable energy used in fracturing rock is directly measured. Ten rock types were tested in uniaxial tension under closed-loop control. Observation of test results and measurements of fracture energy are presented.
