A novel stiffness scaling methodology for discrete element modelling of cohesive fine powders

Yi He et al.

Summary: (English Summary:) The study highlights the importance of considering sliding and rolling resistances as well as non-contact cohesive interaction when modelling cohesive fine powders, presenting a new stiffness scaling methodology that significantly improves the accuracy of simulations. The new approach preserves particle behavior and packing structure details even when stiffness is scaled down by orders of magnitude, demonstrating its applicability in various contact-dominated systems.

The influence of material and process parameters on powder spreading in additive manufacturing

Mohamad Yousef Shaheen et al.

Summary: This study investigates the factors influencing powder layer quality in laser powder bed fusion (LPBF), including the effects of materials and process parameters on spreading, as well as the impact of factors such as particle shape and surface roughness on layer quality. The research reveals that different factors have a significant influence on powder layer quality, and there is a trade-off between material and process parameters.
