Numerical determination of shear stress relaxation modulus of polymer glasses
I. Kriuchevskyi, J. P. Wittmer, O. Benzerara +2
Focusing on simulated polymer glasses well below the glass transition, we confirm the validity and the efficiency of the recently proposed simple-average expression $G(t) = μ_A - h…
Marginally compact hyperbranched polymer trees
M. Dolgushev, J. P. Wittmer, A. Johner +3
Assuming Gaussian chain statistics along the chain contour, we generate by means of a proper fractal generator hyperbranched polymer trees which are marginally compact. Static and…
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…
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…
The role of shape disorder in the collective behaviour of aligned fibrous matter
Salvatore Salamone, Nava Schulmann, Olivier Benzerara +3
We study the compression of bundles of aligned macroscopic fibers with intrinsic shape disorder, as found in human hair and in many other natural and man-made systems. We show by a…
Shear-stress fluctuations and relaxation in polymer glasses
I. Kriuchevskyi, J. P. Wittmer, H. Meyer +2
We investigate by means of molecular dynamics simulation a coarse-grained polymer glass model focusing on (quasi-static and dynamical) shear-stress fluctuations as a function of te…
Fluctuation-dissipation relation between shear stress relaxation modulus and shear stress autocorrelation function revisited
J. P. Wittmer, H. Xu, O. Benzerara +1
The shear stress relaxation modulus may be determined from the shear stress after switching on a tiny step strain or by inverse Fourier transformation of the stor…
