Investigation into the Effects of Prior Plasticity on Creep Accumulation in 316H Stainless Steel
Physical Sciences Forum, 2022 Steel components in the boilers of nuclear reactors are subject to high temperatures and varying loading conditions. This can introduce time-dependent and time-independent plasticity, which can interact with one another.

Influence of the Yield Surface Curvature on the Forming Limit Diagrams Predicted by Crystal Plasticity Theory [PDF]
, 2016 The aim of this paper is to investigate the impact of the microscopic yield surface (i.e., at the single crystal scale) on the forming limit diagrams (FLDs) of face centred cubic (FCC) materials.

A crystal plasticity based approach for the modelling of high cycle fatigue damage in metallic materials [PDF]
, 2016 In this paper, a polycrystalline model is proposed to describe the fatigue behaviour of metallic materials in the high cycle fatigue regime. The model is based on a multiscale approach, which allows the connection of local deformation and damage ...

X-ray microdiffraction and strain gradient crystal plasticity studies of geometrically necessary dislocations near a Ni bicrystal grain boundary [PDF]
, 2009 We compare experimental measurements of inhomogeneous plastic deformation in a Ni bicrystal with crystal plasticity simulations. Polychromatic X-ray microdiffraction, orientation imaging microscopy and scanning electron microscopy, were used to ...

Line-tension model for plasticity as the Gamma-limit of a nonlinear dislocation energy [PDF]
, 2012 In this paper we rigorously derive a line-tension model for plasticity as the Gamma-limit of a nonlinear mesoscopic dislocation energy, without resorting to the introduction of an ad hoc cut-off radius.

Metal Crystal/Polycrystal Plasticity and Strengths
Metals, 2022 A brief historical sketch is given of Taylor’s dislocation density-based model description, leading to the prediction of a parabolic, tensile, stress–strain curve for the plastic deformation of aluminum.

Multiscale modeling of upper mantle plasticity: From single-crystal rheology to multiphase aggregate deformation [PDF]
, 2014 We report a first application of an improved second-order (SO) viscoplastic self-consistent model for multiphase aggregates, applied to an olivine + diopside aggregate as analogue for a dry upper mantle peridotite deformed at 10 15 s 1 shear strain rate ...
