Viscoplastic behavior of metallic materials is manifested by collective behavior of lattice
defects at multiple length scales. The full gamut of length scales, from atomic to …

Although the present edition of Fundamentals of Creep in Metals and Alloys remains broadly
up to date for metals, there are a range of improvements and updates that are either …

The mechanical behavior of nanolaminates is dominated by interfaces that act as sources,
barriers, and preferred sites for storage and dynamic recovery of glide dislocations. In this …

Numerical algorithms for discrete dislocation dynamics simulations are investigated for the
purpose of enabling strain hardening simulations of single crystals on massively parallel …

The noble gases have a particularly stable electronic configuration, comprising fully filled s
and p valence orbitals. This makes these elements relatively non-reactive, and they exist at …

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

Plasticity of irradiated UO 2 is of major interest to improve the risk assessment of the nuclear
fuel cladding failure in the case of design basis accidents. In this study, we investigate the …

Discrete dislocation dynamics is a numerical tool developed to model the plasticity of
crystalline materials at an intermediate length scale, between the atomistic modeling and the …

The irradiation of metals by energetic particles causes significant degradation of the
mechanical properties,, most notably an increased yield stress and decreased ductility, often …

An in-situ transmission electron microscopy straining technique has been used to
investigate the dynamics of dislocation-defect interactions in ion-irradiated copper and the …
