Dataset for time-lapse ultrasonic tomography and FDEM numerical simulation of a uniaxial compression test

Description

This dataset includes raw data from a time-lapse ultrasonic tomography observation and a numerical simulation model. Four data sets are included in this article, and their format and naming conventions are explained in separate files. First, the ultrasonic tomography (UT) data at each 20 MPa intervals during the loading process. Second, the stress-strain data from the uniaxial compression test. Third, the combined finite-discrete element method (FDEM) model used in the manuscript. Last, the simulated AE data extracted from the simulation results.
