A new mechanism for granular segregation

open access: yes, 2001
A novel process is described that produces horizontal size segregation in a vertically vibrated layer of granular material. The behavior is a consequence of two distinct phenomena that are unique to excited granular media: vibration which causes the ...

Peculiarities of Designing the Frame of a Universal Container Made of Rectangular Pipes

open access: yesCommunications
The features of designing the frame of a universal container made of square pipes are presented in this paper. The two frame loading schemes are taken into account: the effect of vertical loading on the container frame when it is lifted by the upper ...
