Automated Dynamic Image Analysis for Particle Size and Shape Classification in Three Dimensions
Sadegh Nadimi, Vasileios Angelidakis, Sadaf Maramizonouz +1
We introduce OCULAR, an innovative hardware and software solution for three-dimensional dynamic image analysis of fine particles. Current state-of-the art instruments for dynamic i…
Alignment-induced depression and shear thinning of anisotropic granular media
Huzaif Rahim, Vasileios Angelidakis, Thorsten Pöschel +1
When granular materials of shape-anisotropic grains are sheared in a split-bottom shear cell, a localized shear band is formed with a depression at its center. This effect is close…
Combined thermal and particle shape effects on powder spreading in additive manufacturing via discrete element simulations
Sudeshna Roy, Hongyi Xiao, Vasileios Angelidakis +1
The thermal and mechanical behaviors of powders are important for various additive manufacturing technologies. For powder bed fusion, capturing the temperature profile and the pack…
SPIRAL: An Efficient Algorithm for the Integration of the Equation of Rotational Motion
Carlos Andrés del Valle, Vasileios Angelidakis, Sudeshna Roy +2
We introduce Spiral, a third-order integration algorithm for the rotational motion of extended bodies. It requires only one force calculation per time step, does not require quater…
Shear zones in granular mixtures of hard and soft particles with high and low friction
Aditya Pratap Singh, Vasileios Angelidakis, Thorsten Pöschel +1
Granular materials show inhomogeneous flows characterized by strain localization. When strain is localized in a sheared granular material, rigid regions of a nearly undeformed stat…
DEM simulation of the powder application in powder bed fusion
Vasileios Angelidakis, Michael Blank, Eric J. R. Parteli +4
The packing behavior of powders is significantly influenced by various types of inter-particle attractive forces, including adhesion and non-bonded van der Waals forces [1, 2, 3, 4…
