The effects of multi-scale particle shape characteristics on the small-strain stiffness of
granular soils remain controversial. This study revisits this topic using well-calibrated three …

The present article designs the granular metamaterials considering the granular structures
of discrete particles which are different from elastic metamaterials consisting of continuous …

The mechanical and rheological behaviour of particulate and granular assemblies is
significantly influenced by the shape of their individual particles. We present a code that …

This paper investigates the micro-to-macro response of granular materials influenced by
multi-scale morphological characteristics using spherical harmonics and LS-DEM. Our …

Soil particles possess highly complex particle morphology, including particle shape and
surface roughness, which have a significant impact on mechanical responses of granular …

Homomorphic filtering (HF) is a methodology that separates an image into two components:
illumination and reflectance. Through the processing of these components, it is possible to …

Particle shape and surface roughness affect both the macro-and micro-mechanical
behaviour of natural sands. In geotechnical practice, the global shape of sands is generally …

In this paper, the validity of the application of an autocorrelation function for resolving some
surface topography measurement problems was presented. Various types of surfaces were …

Studies of surface topography including processes of measurement and data analysis have
an influence on the description of machined parts with their tribological performance …

This contribution investigates the characteristics of elastic wave velocities (V p and V s)
during triaxial shearing tests under dry and drained conditions. Samples of tested materials …
