Interface controlled plastic flow modelled by strain gradient plasticity theory
Comptes Rendus. Mécanique, 2012 The resistance to plastic flow in metals is often dominated by the presence of interfaces which interfere with dislocation nucleation and motion. Interfaces can be static such as grain and phase boundaries or dynamic such as new boundaries resulting from a phase transformation.

Models of nonlinear kinematic hardening based on different versions of rate-independent maxwell fluid [PDF]
, 2017 Different models of finite strain plasticity with a nonlinear kinematic hardening are analyzed in a systematic way. All the models are based on a certain formulation of a rate-independent Maxwell fluid, which is used to render the evolution of backstresses.

Well-posedness for the microcurl model in both single and polycrystal gradient plasticity [PDF]
arXiv, 2016 We consider the recently introduced microcurl model which is a variant of strain gradient plasticity in which the curl of the plastic distortion is coupled to an additional micromorphic-type field. For both single crystal and polycrystal cases, we formulate the model and show its well-posedness in the rate-independent case provided some local hardening

Strain gradient plasticity analysis of transformation induced plasticity in multiphase steels
International Journal of Solids and Structures, 2008 Abstract“To what extent do plastic strain gradients affect the strengthening resulting from the transformation of small metastable inclusions into hard inclusions within a plastically deforming matrix?” is the central question addressed here. Though general in the approach, the focus is on the behavior of TRIP-assisted multiphase steels.

In situ quantitative study of plastic strain-induced phase transformations under high pressure: Example for ultra-pure Zr [PDF]
arXiv, 2019 The first in situ quantitative synchrotron X-ray diffraction (XRD) study of plastic strain-induced phase transformation (PT) has been performed on $\alpha-\omega$ PT in ultra-pure, strongly plastically predeformed Zr as an example, under different compression-shear pathways in rotational diamond anvil cell (RDAC).
