Generation and accumulation of atomic vacancy due to pair annihilation of edge
dislocations during plastic slip deformation of metallic materials are numerically evaluated …

Accurate and reliable predictions of yield surfaces and their evolution with deformation
require a better physical representation of the important sources of anisotropy in the …

Previous study has established that close correlations exist in copper single crystals
between dislocation cells and active slip systems. In grains of a polycrystalline sample …

A long standing challenge in computational materials science is to establish a quantitative
connection between the macroscopic properties of plastic deformation with the microscopic …

A variant of the 3IVM (three internal variables model)[F. Roters, D. Raabe, G. Gottstein, Acta
Mater. 48 (2000) 4181–4189] is presented. It utilizes the microstructural state variables to …

The dynamic internal variables which control plastic flow can only be assessed by dynamic
materials testing at any given instance. The testing method championned by our studies has …

The goal of this work is to formulate a constitutive model for the deformation of metallic
single crystals over a wide range of strain rates, which is integral to computing reliable stress …

A recent strain hardening model for late deformation stages (Estrin, Y., To´ th, LS, Molinari,
A., and Bre´ chet, Y., Acta Materialia, 1998,“A dislocation-based model for all hardening …

Tapered copper single crystals oriented for single slip are deformed plastically at room
temperature and at 77 K. TEM investigations at resolved shear stress levels of 20, 30, and …

We present a crystal plasticity model that incorporates cross-slip of screw dislocations
explicitly based on dislocation densities. The residence plane of screw dislocations is …
