It is argued herein that unconsolidated ice rubble undergoing continuous shear deformation is essentially cohesionless; i.e., in terms of the Mohr-Coulomb failure criterion, it should not exhibit a cohesive intercept at zero confining pressure and at large shear deformation. Contacting pieces of ...
For monosized particulate systems, while cohesionless particles perfectly mix when tumbled, highly cohesive particles segregate. For bidisperse mixtures of particles, an adequate cohesion-tuning reduces segregation and enhances mixing. Based on these results, a simple scheme is proposed to describe the ...
Instead, the vast majority of work has been directed at the study of non-cohesive (i.e., free-flowing) particles, and a wealth of information has been learned about the behavior of cohesionless materials. With growing emphasis on controlling the structure of materials at increasingly small ...
Anisotropy of dry cohesive and cohesionless powders and the effect of particle shape and sample deposition method on the anisotropy were investigated using... F Li,VM Puri - 《Powder Technology》 被引量: 43发表: 1996年 Measurement of Aggregate Cohesion by Tissue Surface Tensiometry Rigorous measure...
Indeed, blocks are not only rigid, but they are also cohesive, whereas granular media are deformable and cohesionless. To shed light on this issue, we ran experiments using two deformable materials of equal density, one exhibiting no cohesion (soft 15-mm-diameter balls) and the other ...
For lower cohesion levels the screen separation performance becomes independent of the level of cohesion level and behaves as if the material is cohesionless.doi:10.1016/j.mineng.2018.01.037Paul W. ClearyCSIRO Data61, Private Bag 10, Clayton South 3168, AustraliaPadarn Wilson...
This counters classical theory that rubble pile asteroids should behave as scale-independent cohesionless collections of rocks. We propose a simple model for asteroid strength that is based on these weak forces, validate it through granular mechanics simulations and comparisons with properties of lunar ...

Here, a material model is used, in which the value of a cohesion factor is used to represent either cohesionless powder or powder with a certain amount of cohesion. It is found that localization under compaction depends strongly on the cohesion factor, the stress state, and the magnitude of ...
As a cohesionless reference, experiments with glass beads were performed. We found that both shape and cohesion exerted about equally strong influence on the angle of repose. We utilized our results for an empirical model that describes the influence of shape and cohesion as additive corrections of...
