Thawed Matrix method for computing Local Mechanical Properties of Amorphous Solids
Jörg Rottler, Céline Ruscher, Peter Sollich
We present a method for computing locally varying nonlinear mechanical properties in particle simulations of amorphous solids. Plastic rearrangements outside a probed region are su…
Tuning the thermal conductivity of silicon nanowires by surface passivation
Céline Ruscher, Robinson Cortes-Huerto, Robert Hannebauer +3
Using large scale molecular dynamics simulations, we study the thermal conductivity of bare and surface passivated silicon nanowires (SiNWs). For the cross-sectional widths $w \le…
Simple generic picture of toughness in solid polymer blends
Debashish Mukherji, Shubham Agarwal, Tiago Espinosa de Oliveira +2
Toughness of a brittle polymeric solid can be enhanced by blending another compatible and ductile polymer. While this common wisdom is generally valid, a generic pict…
Stress overshoot, hysteresis and Bauschinger effect in sheared dense colloidal suspensions
Dmytro Kushnir, Céline Ruscher, Eckhard Bartsch +2
The mechanical non-linear response of dense Brownian suspensions of polymer gel particles is studied experimentally and by means of numerical simulations. It is shown that the resp…
Computational Indentation in Highly Cross-linked Polymer Networks
Manoj Kumar Maurya, Céline Ruscher, Debashish Mukherji +1
Indentation is a common experimental technique to study the mechanics of polymeric materials. The main advantage of using indentation is because this provides a direct correlation…
Correlating thermodynamics, morphology, mechanics and thermal transport in PMMA-PLA blends
Debashish Mukherji, Tiago Espinosa de Oliveira, Celine Ruscher +1
Thermodynamics controls structure, function, stability and morphology of polymer blends. However, obtaining the precise information about their mixing thermodynamics is a challengi…
Ripple-like instability in the simulated gel phase of finite size phosphocholine bilayers
Vivien Walter, Céline Ruscher, Adrien Gola +3
Atomistic molecular dynamics simulations have reached a degree of maturity that makes it possible to investigate the lipid polymorphism of model bilayers over a wide range of tempe…
Avalanches in the athermal quasistatic limit of sheared amorphous solids: an atomistic perspective
Céline Ruscher, Jörg Rottler
We study the statistical properties of the yielding transition in model amorphous solids in the limit of slow, athermal deformation. Plastic flow occurs via alternating phases of e…
Signatures of the spatial extent of plastic events in the yielding transition in amorphous solids
Daniel Korchinski, Céline Ruscher, Jörg Rottler
Amorphous solids are yield stress materials that flow when a sufficient load is applied. Their flow consists of periods of elastic loading interrupted by rapid stress drops, or ava…
Glassy dynamics of a binary Voronoi fluid: A mode-coupling analysis
Céline Ruscher, Simone Ciarella, Chengjie Luo +3
The binary Voronoi mixture is a fluid model whose interactions are local and many-body. Here we perform molecular-dynamics (MD) simulations of an equimolar mixture that is weakly p…
Elasticity and thermal transport of commodity plastics
Celine Ruscher, Joerg Rottler, Charlotte Boott +2
Applications of commodity polymers are often hindered by their low thermal conductivity. In these systems, going from the standard polymers dictated by weak van der Waals interacti…
Residual stress distributions in athermally deformed amorphous solids from atomistic simulations
Céline Ruscher, Jörg Rottler
The distribution of local residual stresses (threshold to instability) that controls the statistical properties of plastic flow in athermal amorphous solids is examined with an ato…
A machine learning assessment of the two states model for lipid bilayer phase transitions
Viven Walter, Céline Ruscher, Olivier Benzerara +2
We have adapted a set of classification algorithms, also known as Machine Learning, to the identification of fluid and gel domains close to the main transition of dipalmitoyl-phosp…
Correlations in the shear flow of athermal amorphous solids: A principal component analysis
Céline Ruscher, Jörg Rottler
We apply principal component analysis, a method frequently used in image processing and unsupervised machine learning, to characterize particle displacements observed in the steady…
Voronoi Glass-Forming Liquids : A Structural Study
Céline Ruscher, Joerg Baschnagel, Jean Farago
We introduce a new theoretical model of simple fluid, whose interactions, defined in terms of the Voronoi cells of the configurations, are local and many-body. The resulting system…
Controlling Marangoni induced instabilities in spin-cast polymer films: how to prepare uniform films
Paul D. Fowler, Celine Ruscher, Joshua D. McGraw +2
In both research and industrial settings spin coating is extensively used to prepare highly uniform thin polymer films. However, under certain conditions, spin coating results in f…
