.... Calcareous soils are always characterized by complex microstructures in terms of loose fabric, irregular particle shapes and abundant intra-particle pores. Therefore, the aim of this study is to establish autonomous particle shape categorization criteria for calcareous soils, and further facilitate...

...Xin Liu; SA LI; TING YAO Particle strength is one of the critical factors that causes the degradation of the mechanical behaviour of crushable soil. Because of the complexity of particle shape, its effect on particle strength has not been completely understood. In this study, single particle...

...Usman Ali; Mamoru Kikumoto; Matteo Ciantia; Marco Previtali; Ying Cui The effect of particle shape on micro and macroscopic behaviour is investigated experimentally through a series of biaxial compression tests on round and angular rods. Dual-size assemblies of thousands of circular (round...

... time; also significant particle breakage occurred at the centre of the specimen during the post-peak stage. The particle shape and gradation analyses reveal that larger grains with lower values of sphericity and convexity are prone to breakage, with the angularities of the crushed particles being...
