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…
Predicting plasticity of amorphous solids from instantaneous normal modes
Ivan Kriuchevksyi, Tim Sirk, Alessio Zaccone
We present a mathematical description of amorphous solid deformation and plasticity by extending the concept of instantaneous normal modes (INMs) to deformed systems, which allows…
Plasticity in amorphous solids is mediated by topological defects in the displacement field
Matteo Baggioli, Ivan Kriuchevskyi, Timothy W. Sirk +1
The microscopic mechanism by which amorphous solids yield plastically under an externally applied stress or deformation has remained elusive in spite of enormous research activity…
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 modulus and shear-stress fluctuations in polymer glasses
I. Kriuchevskyi, J. P. Wittmer, H. Meyer +1
Using molecular dynamics simulation of a standard coarse-grained polymer glass model we investigate by means of the stress-fluctuation formalism the shear modulus as a function…
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…
