Nonmonotonic Strain Rate Dependence on the Strain Hardening of Polymer Nanocomposites

open access: yesACS Macro Letters, 2020
This Letter investigates the external deformation on modifying the polymer-nanoparticle (NP) and NP-NP interactions as well as their influences on the macroscopic properties of polymer nanocomposites (PNCs). Specifically, the applied uniaxial extension brings together the NPs along the transverse stretching direction and catalyzes the percolation ...

The strain and strain rate dependence of the yield stress of aluminum [PDF]

open access: yesDiagnostics, Resource and Mechanics of materials and structures, 2021
The plastic properties of aluminum (99.5 %) are considered. Using the hardening curves (for strain rates of 0.25, 0.4, and 63.0 s −1), analytic dependences of the yield stress of aluminum on strain (in the range between 0.0 and 0.5) and strain rate (in the range between 0.25 and 63.0 s−1) have been found.
