Dislocation mediated plastic flow in aluminum: comparison between theory and experiment

TL;DR

This paper applies a dislocation-mediated plastic flow theory to aluminum, successfully predicting stress-strain behavior across various temperatures and strain rates with high accuracy.

Contribution

It demonstrates the effectiveness of the Langer, Bouchbinder, and Lookman theory in modeling aluminum's plastic flow, validated by experimental data.

Findings

Excellent agreement between theory and experiment

Accurate prediction of stress-strain curves across conditions

Validation of dislocation-mediated plastic flow model

Abstract

The theory of dislocation mediated plastic flow proposed by Langer, Bouchbinder, and Lookman is applied to compute the stress-strain curve of aluminum and aluminum alloys over a wide range of temperatures and strain rates. The comparison with experiment shows excellent agreement.
