Strain correlation functions in isotropic elastic bodies: Large wavelength limit for two-dimensional systems
J. P. Wittmer, A. N. Semenov, J. Baschnagel
Strain correlation functions in two-dimensional isotropic elastic bodies are shown both theoretically (using the general structure of isotropic tensor fields) and numerically (usin…
Correlations of tensor field components in isotropic systems with an application to stress correlations in elastic bodies
J. P. Wittmer, A. N. Semenov, J. Baschnagel
Correlation functions of components of second-order tensor fields in isotropic systems can be reduced to an isotropic forth-order tensor field characterized by a few invariant corr…
Spatial correlation functions for non-ergodic stochastic processes of macroscopic system
J. P. Wittmer, A. N. Semenov, J. Baschnagel
Focusing on non-ergodic macroscopic systems we reconsider the variances of time averages time-series. The total variance (direct average over all time-series) is known to be the su…
Simple models for strictly non-ergodic stochastic processes of macroscopic systems
G. George, L. Klochko, A. N. Semenov +2
We investigate simple models for strictly non-ergodic stochastic processes ( being the discrete time step) focusing on the expectation value and the standard deviation…
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…
Shear-stress fluctuations in self-assembled transient elastic networks
J. P. Wittmer, I. Kriuchevskyi, A. Cavallo +2
Focusing on shear-stress fluctuations we investigate numerically a simple generic model for self-assembled transient networks formed by repulsive beads reversibly bridged by ideal…
