Mechanical momentum transfer in wall-bounded superfluid turbulence
D. Khomenko, V. S. L'vov, A. Pomyalov +1
In classical turbulence the kinematic viscosity is involved in two phenomena. The first is the energy dissipation and the second is the mechanical momentum flux toward the wall…
Elasticity in Amorphous Solids: Nonlinear or Piece-Wise Linear?
Awadhesh K. Dubey, Itamar Procaccia, Carmel A. B. Z. Shor +1
Quasi-static strain-controlled measurements of stress vs strain curves in macroscopic amorphous solids result in a nonlinear looking curve that ends up either in mechanical collaps…
Microalloying and the mechanical properties of amorphous solids
H. George E. Hentschel, Michael Moshe, Itamar Procaccia +1
The mechanical properties of amorphous solids like metallic glasses can be dramatically changed by adding small concentrations (as low as 0.1\%) of foreign elements. The glass-form…
Stochastic Approach to Plasticity and Yield in Amorphous Solids
H. G. E. Hentschel, Prabhat K. Jaiswal, Itamar Procaccia +1
We focus on the probability distribution function (pdf) where are the {\em measured} strain intervals between plastic events in an athermal strained amorphous solid…
Counter-flow Induced Decoupling in Super-Fluid Turbulence
Dmytro Khomenko, Victor S. L'vov, Anna Pomyalov +1
In mechanically driven superfluid turbulence the mean velocities of the normal- and superfluid components are known to coincide: . Numer…
Consequences of Disorder on the Stability of Amorphous Solids
Vladimir Dailidonis, Valery Ilyin, Pankaj Mishra +1
Highly acurate numerical simulations are employed to highlight the subtle but important differences in the mechanical stability of perfect crystalline solids versus amorphous solid…
