Abstract: This paper presents an in-depth study on the particle breakage behavior within a miniature specimen of highly decomposed granite (HDG) subject to one-dimensional compression with in-situ x-ray microtomography. Through a full-field particle tracking analysis of almost all broken and unbroken particles enabled by the SHOT++ technique, authors revealed various particle-scale phenomena related to particle breakage including evolutions of particle shape, fragmentation pattern, and coordination number. SHOT++, which is formed by integrating the iterative closest point algorithm and the random sample consensus algorithm into the signature of histograms of orientation (SHOT) algorithm, first distinguishes the original surfaces of a broken particle from its fracture surfaces, then encodes its morphological information using the SHOT descriptor, and finally determines the optimal match and the transformation matrix to its original particle. The high tracking accuracy of SHOT++ allows it to track the movements of most of all broken and unbroken particles throughout the test and thus to reveal unprecedented insights into the microscopic mechanisms underlying the macroscopic compression behavior of HDG.
