The increasingly harsh environment of the nuclear reactors and the insurmountable flaws of
in-service materials have created an urgent need for the development of the brand-new …

It has long been recognized that exposure to irradiation environments could dramatically
degrade the mechanical properties of nuclear structural materials, ie, irradiation-hardening …

Particularly in plastically anisotropic crystals, such as hexagonal close packed (HCP)
materials, plastic deformation is realized by slip acting in the small volumes within individual …

Using a combination of mechanical testing, scanning electron microscopy, and a unified
crystal plasticity framework for discrete intragranular shear localization, we investigate …

The ability of softening strain gradient plasticity to simulate intragranular plastic slip
localization modes called slip and kink bands, at is investigated at incipient plasticity. A …

In this work, an integrated approach including experimental examinations and theoretical
modeling was employed to examine the temperature-dependent hardening of structural …

Radiation damage introduces a wide range of defects in structural materials depending on
the irradiation conditions. Irradiation-induced loops are known to lead to dislocation …

A new computational methodology for 3-dimensional (3D) Discrete Dislocation Dynamics
(DDD) in barrier-strengthened materials is developed. We couple the discrete 3D DDD …

Incipient slip localization in the vicinity of hundreds of grain boundary triple junctions (TJs) in
a lightly deformed nickel-base superalloy IN718 is studied using a combination of three …

Size-dependent yield strength is a common feature observed in miniaturized crystalline
metallic samples, and plenty of studies have been conducted in experiments and numerical …
