Simple-average expressions for shear-stress relaxation modulus
J. P. Wittmer, H. Xu, J. Baschnagel
Focusing on isotropic elastic networks we propose a novel simple-average expression for the computational determination of the shear-stress relaxation modulus $…
Hyperbranched polymer stars with Gaussian chain statistics revisited
P. Polinska, C. Gillig, J. P. Wittmer +1
Conformational properties of regular dendrimers and more general hyperbranched polymer stars with Gaussian statistics for the spacer chains between branching points are revisited n…
Compressibility and pressure correlations in isotropic solids and fluids
J. P. Wittmer, H. Xu, P. Polinsak +4
Presenting simple coarse-grained models of isotropic solids and fluids in , and dimensions we investigate the correlations of the instantaneous pressure and its ideal…
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…
Shear stress relaxation and ensemble transformation of shear stress autocorrelation functions revisited
J. P. Wittmer, H. Xu, J. Baschnagel
We revisit the relation between the shear stress relaxation modulus , computed at finite shear strain , and the shear stress autocorrelation functions a…
