Densely packed particle raft at vertically vibrated air-water interface
Xiuhe Yan, Tabitha C. Watson, Hongyi Xiao
We investigate the dynamics of a dense raft of millimeter-sized granular particles at a vertically vibrated air-water interface, which displays a rich set of patterns and particle…
Reciprocal swimming in viscoelastic granular hydrogels
Hongyi Xiao, Jing Wang, Achim Sack +2
We experimentally study a scallop-like swimmer with reciprocally flapping wings in a nearly frictionless, cohesive granular medium consisting of hydrogel spheres. Significant locom…
Reciprocal swimming in granular media: the role of jamming and swimmer inertia
Amir Nazemi, Hongyi Xiao
We use particle simulations to reveal two distinct propulsion mechanisms for a scallop-like swimmer to propel itself in granular media by reciprocally flapping its wings. Based on…
Locomotion of a Scallop-Inspired Swimmer in Granular Matter
Hongyi Xiao, Harol Torres, Achim Sack +1
Understanding swimming in soft yielding media is challenging due to their complex deformation response to the swimmer's motion. We experimentally show that a scallop-inspired swimm…
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…
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…
Structural fluctuations in thin cohesive particle layers in powder-based additive manufacturing
Sudeshna Roy, Hongyi Xiao, Vasileios Angelidakis +1
Producing dense and homogeneous powder layers with smooth free surface is challenging in additive manufacturing, as interparticle cohesion can strongly affect the powder packing st…
