Ellipticity loss analysis for tangent moduli deduced from a large strain elastic–plastic self-consistent model [PDF]
, 2009 In order to investigate the impact of microstructures and deformation mechanisms on the ductility of materials, the criterion first proposed by Rice is applied to elastic–plastic tangent moduli derived from a large strain micromechanical model combined ...

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 ...

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.

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 ...
