On inequalities of shear modulus contributions in disordered elastic bodies
J. P. Wittmer, H. Xu
We investigate generic inequalities of various contributions to the shear modulus in ensembles of amorphous elastic bodies. We focus first on a simple elastic network model wit…
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…
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 $…
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…
