In the construction and operation of underground pipelines, feasibility engineering methods protecting insulation coating from external mechanical impacts should be based on existing loads. When an pipeline is laid coarse gravel very soil, analysis support forces at base a pressing issue. particular, difficult conditions for construction, reconstruction, repair pipelines include cases when rout...

The spheropolyhedra method has been used earlier for efficient and accurate molecular dynamics simulations of granular matter with particles with complex shapes. Also the Voronoi construction is a tool of proved utility for the virtual representation of powders and grains. In this paper a technique that combines the two methods and provides a framework for the study of the three-dimensional mec...
