Micromechanical Analysis of Compaction and Drilling of Granular Media- A Review
Abstract: Granular matter is ubiquitous in our daily life yet far from completely understood. These granular materials have constituted a class of complex systems which exhibit global behaviors been reminiscent of solids, liquids, gases, or otherwise uniquely their own. The key to achieve good properties lies in the material structure from the molecules, via structures on nano- and micro levels to the macroscopic material. This paper also reviewed selected approaches and …
