This contribution assesses the effect of particle surface roughness on the shear wave
velocity (VS) and the small-strain stiffness (G 0) of soils using both laboratory shear plate …

The nature of soil stiffness at small strains remains poorly understood. The relationship
between soil stiffness (eg shear stiffness, G 0) and isotropic confining pressure (p′) can be …

Sand roughness is now accessible to measurement. Incorporating this parameter into sand
models using the discrete element method (DEM) is known to improve bulk small strain …

Discrete-element method (DEM) simulations of planar wave propagation are used to
examine the effect of particle surface roughness on the stiffness and dynamic response of …

Accurate design of geotechnical structures requires precise estimation of the shear wave
velocity (V s) and the small-strain shear modulus. However, the interpretation of V s data …

In comparison to the description of particle size and shape, the surface roughness, which
mainly affects the inter-particle friction, is more difficult to measure and quantify. One …

Soils are granular materials consisting of many particles, and the overall response of a soil
can be considered to be a complex accumulation of the inter-particle responses. Small …

Particles slide and roll on each other when a granular medium is sheared. Consequently,
the tribological properties, such as inter-particle friction and adhesion, play a major role in …

Our understanding of the mechanics of contact behaviour for interacting particles has been
developed mostly assuming that surfaces are smooth. However, real particles of interest in …

It is empirically known that the packing property and mechanical responses of cohesionless
granular materials are influenced by grain shape. For example, the attainable range of void …
