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…
Machine learning-informed structuro-elastoplasticity predicts ductility of disordered solids
Hongyi Xiao, Ge Zhang, Entao Yang +5
All solids yield under sufficiently high mechanical loads. Below yield, the mechanical responses of all disordered solids are nearly alike, but above yield every different disorder…
Modeling Stratified Segregation in Periodically Driven Granular Heap Flow
Hongyi Xiao, Zhekai Deng, Julio M. Ottino +2
We present a continuum approach to model segregation of size-bidisperse granular materials in unsteady bounded heap flow as a prototype for modeling segregation in other time varyi…
