DOI: 10.1038/s41598-020-62827-w
Abstract: Particle shape analysis is conducted, to compare two types of railway ballast: Calcite and Kieselkalk. Focus lies on the characterisation of particle angularity using 3D scanner data. In the literature, angularity is often characterised using… read more here.

DOI: 10.1038/s41598-024-79400-4
Abstract: Several studies reported various crossmodal correspondences related to tactile features. These previous studies have investigated tactile-related correspondences through explicit matching or subjective evaluation tasks, which required participants to recognize relationships between tactile and other sensory… read more here.

DOI: 10.1080/10298436.2024.2427275
Abstract: ABSTRACT Aggregates used in civil engineering are irregular-shaped granular materials. Angularity is an important shape feature of aggregates (and for various other granular materials). Various alternative approaches are available in the literature on quantitative estimation… read more here.

DOI: 10.1103/physreve.111.015407
Abstract: Employing extensive 2D contact dynamics simulations, we analyze the effects of grain shape angularity on the quasistatic shear strength properties of cohesive granular packings. We consider sticky irregular polygons ranging from disklike shapes to triangle.… read more here.

DOI: 10.3390/ma13020492
Abstract: Under the repeated loading, the continuous impact and friction of tires on aggregates resulted in some changes in their morphology, which may cause rutting, decrease in skid resistance, and fatigue damage of the road. In… read more here.
