The theory of work hardening has had a turbulent history. In 1953, Cottrell [1] remarked that
''it was the first problem to be attempted by dislocation theory and may be the last to be …

Lightweight sheet metals are attractive for aerospace and automotive applications due to
their exceptional properties, such as low density and high strength. Sheet metal forming …

In this paper, anisotropic yield functions based on linear transformations of the stress
deviator are discussed in general terms. Two specific convex formulations are proposed to …

In this work, a single crystal constitutive law for multiple slip and twinning modes in single
phase hcp materials is developed. For each slip mode, a dislocation population is evolved …

Severe plastic deformation (SPD) has established itself as a potent means of producing bulk
ultrafine grained and nanostructured materials. It has given rise to burgeoning research that …

The paper reports on a recent effort to develop a statistical (or Monte-Carlo) model for
quantitative deformation texture prediction which is yet fast enough for implementation in …

The accelerating rate at which new materials are appearing, and transforming the
engineering world, only serves to emphasize the vast potential for novel material structure …

In the past twenty years, new experimental approaches, improved models and progress in
simulation techniques have brought new insights into longstanding issues concerning …

The detailed contribution of microstructural-level phenomena, such as dislocation structure
development and annihilation, as well as inter-granular and intra-granular backstress fields …

This paper proposes a yield function to model sheet metal strength between shear and
plane strain tension. The function is expressed as an equation of the three stress invariants …
