Nanoscale linear response of strongly disordered stable solids
D. V. Babin, I. O. Raikov, Y. M. Beltukov
Strongly disordered solids exhibit distinctive properties at the nanoscale, where conventional continuum theory breaks down. We show that their disorder-averaged linear response ca…
Comparative analysis of nonlinear elastic moduli of polystyrene, polycarbonate and PMMA
A. V. Belashov, A. A. Zhikhoreva, Y. M. Beltukov +1
We present the comparative experimental analysis of frequency dependencies of linear (Lamé) and nonlinear (Murnaghan) elastic moduli of polystyrene, PMMA and polycarbonate. The me…
Large-scale exponential correlations of nonaffine elastic response of strongly disordered materials
D. A. Conyuh, D. V. Babin, I. O. Raikov +1
The correlation properties of the nonaffine elastic response in strongly disordered materials are investigated using the theory of correlated random matrices and supported by numer…
Non-perturbative macroscopic theory of interfaces with discontinuous dielectric constant
Y. M. Beltukov, A. V. Rodina, A. Alekseev +1
Discontinuity of dielectric constants at the interface is a common feature of all nanostructures and semiconductor heterostructures. Near such interfaces, a charged particle create…
Temperature dependence of nonlinear elastic moduli of polystyrene
Andrey V. Belashov, Anna A. Zhikhoreva, Yaroslav M. Beltukov +1
Nonlinear elastic properties of polymers and polymeric composites are essential for accurate prediction of their response to dynamic loads, which is crucial in a wide range of appl…
Slowly decaying strain solitons in nonlinear viscoelastic waveguides
F. E. Garbuzov, Y. M. Beltukov
This paper is devoted to the modeling of longitudinal strain waves in a rod composed of a nonlinear viscoelastic material characterized by frequency-dependent second- and third-ord…
