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…
Shear-stress fluctuations in free-standing polymer films
G. George, I. Kriuchevskyi, H. Meyer +2
Using molecular dynamics simulation of a polymer glass model we investigate free-standing polymer films focusing on the in-plane shear modulus and the corresponding shear-stres…
Scale-free center-of-mass displacement correlations in dense polymer solutions and melts without topological constraints and momentum conservation: A bond-fluctuation model study
Joachim P. Wittmer, Patrycia Polińska, Anna Cavallo +4
By Monte Carlo simulations of a variant of the bond-fluctuation model without topological constraints we examine the center-of-mass (COM) dynamics of polymer melts in dimensi…
Static Properties of Polymer Melts in Two Dimensions
H. Meyer, J. P. Wittmer, T. Kreer +2
Self-avoiding polymers in strictly two-dimensional () melts are investigated by means of molecular dynamics simulation of a standard bead-spring model with chain lengths rangi…
Distance dependence of angular correlations in dense polymer solutions
J. P. Wittmer, A. Johner, S. P. Obukhov +3
Angular correlations in dense solutions and melts of flexible polymer chains are investigated with respect to the distance between the bonds by comparing quantitative predictio…
