Machine Learning for the identification of phase-transitions in interacting agent-based systems: a Desai-Zwanzig example
Nikolaos Evangelou, Dimitrios G. Giovanis, George A. Kevrekidis +2
Deriving closed-form, analytical expressions for reduced-order models, and judiciously choosing the closures leading to them, has long been the strategy of choice for studying phas…
Contact behaviour of simulated rough spheres generated with spherical harmonics
Deheng Wei, Chongpu Zhai, Dorian A. H. Hanaor +1
Normal contact behaviour between non adhesive fractal rough particles is studied using a finite element method (FEM). A series of spherical grain surfaces with distinguished roughn…
Understanding the effect of hyperparameter optimization on machine learning models for structure design problems
Xianping Du, Hongyi Xu, Feng Zhu
To relieve the computational cost of design evaluations using expensive finite element simulations, surrogate models have been widely applied in computer-aided engineering design.…
Predicting plasticity in disordered solids from structural indicators
D. Richard, M. Ozawa, S. Patinet +16
Amorphous solids lack long-range order. Therefore identifying structural defects -- akin to dislocations in crystalline solids -- that carry plastic flow in these systems remains a…
Elastic deformation during dynamic force measurements in viscous fluids
Yumo Wang, Georgia Pilkington, Charles Dhong +1
Understanding and harnessing the coupling between lubrication pressure and elasticity provides materials design strategies for applications such as adhesives, coatings, microsensor…
Morphology of soft and slippery contact via fluid drainage
Yumo Wang, Joelle Frechette
The dynamic of contact formation between soft materials immersed in a fluid is accompanied by fluid drainage and elastic deformation. As a result, controlling the coupling between…
Critical Analysis of an FeP Empirical Potential Employed to Study Fracture of Metallic Glasses
Yezeng He, Peng Yi, Michael L. Falk
An empirical potential that has been widely used to perform molecular dynamics studies on the fracture behavior of FeP metallic glasses is shown to exhibit spinodal decomposition i…
Shear Band Broadening in Simulated Glasses
Darius D. Alix-Williams, Michael L. Falk
Two models are proposed to predict the evolution of shear band width as a function of applied strain for simulated glasses mechanically deformed in simple shear. The first model ar…
Stress-dependent electrical transport and its universal scaling in granular materials
Chongpu Zhai, Dorian Hanaor, Gwénaëlle Proust +1
We experimentally and numerically examine stress-dependent electrical transport in granular materials to elucidate the origins of their universal dielectric response. The ac respon…
Out-of-contact elastohydrodynamic deformation due to lubrication forces
Yumo Wang, Charles Dhong, Joelle Frechette
We characterize the spatiotemporal deformation of an elastic film during the radial drainage of fluid from a narrowing gap. Elastic deformation of the film takes the form of a dimp…
Shearing a glass and the role of pin-delay in models of interface depinning
Stefanos Papanikolaou
When a disordered solid is sheared, yielding is followed by the onset of intermittent response that is characterized by slip in local regions usually labeled shear-transformation z…
