Fragmentation modes of single coral particles under uniaxial compression: Microstructural insights

Xianwei Zhang et al.

Summary: This paper explores the particle breakage behavior of coral soil and its relationship with microstructural characteristics. The study finds that the fragmentation mode of coral particles is mainly influenced by microstructure, with particle irregularity also playing a role. Underwater immersion reduces the particle crushing strength and leads to more breakage. Additionally, a fragmentation mode classification system that considers force-displacement responses, particle fragmentation features, and microstructural properties is proposed.

Effects of size and shape on the crushing strength of coral sand particles under diametral compression test

Wu Xuehui et al.

Summary: The study used the Weibull statistical method to analyze the crushing strength of coral sand particles, finding relationships between particle breakage types and strength, inverse correlation between particle size and strength, positive correlation between circularity and strength, as well as positive correlation between equancy and strength.
