Abstract. The coefficient of earth pressure at rest (K_ {0}) of granular soils is revisited by discrete element method simulation. The effects of confining pressure, soil density and over-consolidation ratio (OCR) on the (K_ {0}) value are investigated. The coefficients of earth pressure at rest defined in the conventional form (K_ {0 ...

Sand production is a complex phenomenon caused by the erosion of borehole walls during the extraction of hydrocarbons. In this paper, the sanding process in a typical Thick-Walled Hollow Cylinder (TWHC) test is numerically simulated. The main objective of the study is to model the particulate mechanism of sand production in …

Aggregate production dates back to the Roman Empire, and it has been critical to the growth of our world ever since. Essentially, they are the most basic material used in construction. They provide the foundation for roads, bridges, and buildings, while also making up over 90% of an asphalt pavement and up to 80% of a concrete mix.
Granular media (granulars) are common both in nature and technology and have been intensely studied [1,2,3], attracting a still growing theoretical interest [4, 5].There is a number of different testing methods suggested for determining various aspects of their behaviour [6, 7].Depending on the conditions (material type and history, stress level, …
