Determining rock crack stress thresholds using ultrasonic through-transmission measurements
Abstract The crack initiation stress threshold is widely used in excavation industries as rock spalling strength when designing deep underground structures to avoid unwanted brittle failures. While various strain-based methods have been developed for the estimation of this critical design parameter,...
