First SCI paper published in JGGE

Exploration of the survival probability and shape evolution of crushable particles during one-dimensional compression using dyed gypsum particles

This paper is Jidu’s first SCI publication, completed during his master’s studies at Hohai University and published in the ASCE Journal of Geotechnical and Geoenvironmental Engineering, one of the leading journals in geotechnical engineering.

Observing how individual particles fragment within a granular assembly is of both theoretical and practical importance. In this study, we introduced a new technique using dyed gypsum particles that allows broken fragments to be matched to their parent particles, together with an image-based method that captures particle shape from two orthogonal views.

One-dimensional compression tests showed that medium-sized particles in polydisperse samples break more than other particles, likely due to the combined effects of crushing strength and coordination number. Broken and surviving particles showed opposite trends in shape evolution. Single-particle crushing tests further suggested that breakage-induced shape irregularity does not change the Weibull modulus but strongly affects the survival probability.

Jidu sincerely thanks Dr. Chaomin Shen, Prof. Sihong Liu and Prof. Yi Pik (Helen) Cheng, who hosted his visit to University College London in 2019, for their guidance on this work.
