The performance and deformation of ballast bed are significantly influenced by the particle
morphology (size and shape), the rheology (translation and rotation), and the degradation …

Soil compaction not only reduces available pore volume in which fluids are stored, but it
alters the arrangement of soil constituents and pore geometry, thereby adversely impacting …

Sand, rice, sugar, snow, cement... Although ubiquitous in our daily lives, granular media still
challenge engineers and fascinate researchers. This book provides the state-of-the-art of the …

We investigate highly polydisperse packings subjected to simple shear by contact dynamics
simulations. A major unsolved issue is how granular texture and force chains depend on the …

Cement setting and cohesion are governed by the precipitation and growth of calcium-
silicate-hydrate, through a complex evolution of microstructure. A colloidal model to describe …

Filter layers are extensively employed in dam structures as a mitigation method against
internal erosion, which facilitates the interlocking and clogging of the suffused base soil due …

We present a numerical analysis of the effect of particle elongation on the quasistatic
behavior of sheared granular media by means of the contact dynamics method. The particle …

By means of contact dynamic simulations, we investigate the contact network topology and
force chains in two-dimensional packings of elongated particles subjected to biaxial …

We present a systematic numerical investigation of the shear strength and structure of
granular packings composed of irregular polyhedral particles. The angularity of the particles …

Particulate materials, such as sandy soil, are everywhere in nature and form the basis for
many engineering applications. The aim of this research is to investigate the particle shape …
