Structured force reformulation of many-body dispersion: towards effective atom--atom decomposition and surrogate modeling
Zhaoxiang Shen, Raúl I. Sosa, Stéphane P. A. Bordas +2
We present a structured force reformulation of the many-body dispersion (MBD) model that enables a physically consistent decomposition of forces into pairwise components. By introd…
Machine learning surrogate models of many-body dispersion interactions in polymer melts
Zhaoxiang Shen, Raúl I. Sosa, Jakub Lengiewicz +2
Accurate prediction of many-body dispersion (MBD) interactions is essential for understanding the van der Waals forces that govern the behavior of many complex molecular systems. H…
A Fully Discrete Element Approach for Modeling Vacuum Packed Particle Dampers
Pawel Chodkiewicz, Robert Zalewski, Jakub Lengiewicz
In this work, we investigate Vacuum-Packed Particle (VPP) dampers -- granular-core dampers offering tunable damping performance -- as a more sustainable alternative to conventional…
Gaussian process regression + deep neural network autoencoder for probabilistic surrogate modeling in nonlinear mechanics of solids
Saurabh Deshpande, Hussein Rappel, Mark Hobbs +2
Many real-world applications demand accurate and fast predictions, as well as reliable uncertainty estimates. However, quantifying uncertainty on high-dimensional predictions is st…
