Particle breakage and shape evolution of calcareous and quartz sands under compression
Yantu gongcheng xuebao, 2022 The influences of particle breakage on the mechanical properties of soil are significant. The previous studies mainly focus on the variation of particle size during particle breakage but neglect the change of particle shape.
