Interactive Role of Rolling Friction and Cohesion on the Angle of Repose through a Microscale Assessment

Thao Doan et al.

Summary: This study investigates the influence of cohesion and rolling friction on the angle of repose (AoR) in soil using the discrete-element method (DEM). The results show that a large AoR can only be obtained when both cohesion and rolling friction are present. Increasing cohesion and rolling friction leads to smaller contact numbers, chain-like connections between particles, and larger pore spaces, resulting in a larger AoR.

Parametric study and calibration of hysteretic spring and linear cohesion contact models for cohesive soils using definitive screening design

Rohit Dilip Nalawade et al.

Summary: Discrete element modelling (DEM) is a popular technique for modelling discontinuous and granular materials. This research proposes a novel DOE approach called definitive screening design (DSD) for parameterization and screening of the most influential DEM parameters. The results show the effect of yield strength, static friction factors, energy density, and stiffness factor on cone index (CI). The parameters were then optimized using central composite design (CCD), and the developed model showed reasonable agreement with observed values.

Electrostatics of granules and granular flows: A review q

Yanlin Zhao et al.

Summary: In recent decades, the electrostatics of granules and granular flows has gained increasing attention due to its relevance to industrial problems and the development of new technologies. Electrification caused by granule-wall collision is influenced by various factors and shows saturation as granule processing increases. The presence of electrostatic charges has significant impacts in chemistry, chemical engineering, energy, pharmaceuticals, and other related areas. The measurement technology of electrostatics in granule conveying systems has been improved, and further research in this interdisciplinary problem is expected.

Calibration of wet sand and gravel particles based on JKR contact model

Jiacheng Zhou et al.

Summary: The parameters of wet sand and gravel particles with different shapes are calibrated based on the JKR contact model. Surface energy and rolling friction coefficient are found to be significant factors affecting the simulation accuracy of wet sand and gravel particles during vibration screening. The non-spherical model and JKR model are proven to better simulate the screening process, and the optimum filling ball radii for different particle shapes are determined.

Evaluation of the significance of the contact model particle parameters in the modelling of wet soils by the discrete element method

Salavat Mudarisov et al.

Summary: Modeling the tillage process using the method of discrete elements shows promise in accurately describing soil behavior, although calibration of the contact model parameters can be time-consuming. The results of calibration help in understanding the significance of these parameters and can lead to nomograms for selecting appropriate parameters based on soil conditions.

Summary: This paper investigates the necessity for accurately calibrating the coefficients of rolling friction between maize seed particles and between the particles and the boundary in DEM simulations.
