Abstract
The mechanical behaviors of the two-dimensional uniform assembly of circular elements are studied by a simple model experiment and the rigid plastic limit analysis. In the experiment, the deformation patterns and the load-settlement curves of the partially-loaded ground are observed using the brass cylinders as the model of granular material while the frictional slippage and the rotation are assumed at the contact points of two elements in the rigid plastic numerical analysis. The comparison between the experiment and the analysis is quite interesting and discussed from a view point of applied mechanics.
