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

The theory of dislocation mediated plastic flow proposed by Langer, Bouchbinder, and Lookman is applied to compute the stress-strain curve of aluminum over a wide range of temperatures and strain rates. The parameter identification by the least squares method is provided leading to the excellent agr...

Description
Summary:The theory of dislocation mediated plastic flow proposed by Langer, Bouchbinder, and Lookman is applied to compute the stress-strain curve of aluminum over a wide range of temperatures and strain rates. The parameter identification by the least squares method is provided leading to the excellent agreement with experiment.
