Generalized model of incipient plasticity with parametric variations
Sweta Kumari, Aditya Vardhan Mishra, Amlan Dutta
Incipient plasticity is typically associated with thermally activated events like the nucleation of dislocations in crystalline solids and the activation of shear transformation zo…
Nucleation of twinning dislocation loops in fcc metals
Sweta Kumari, Amlan Dutta
Deformation twinning, which occurs in fcc metals only under particular conditions of intrinsic material properties, microstructure, and loading conditions, occupies an indispensabl…
Core-structure and lattice resistance of twinning dislocations in fcc metals
Sri Sadgun Reddy Pulagam, Amlan Dutta
Metals with fcc structure may exhibit deformation twinning under specific conditions, which is an interesting but somewhat elusive aspect of their deformation behavior. It is well…
Compressive deformation of Fe nanopillar : Modalities of dislocation dynamics
Amlan Dutta
Unlike the tensile mode, compressive deformation of a bcc metallic nanostructure is mediated by the glide of screw dislocation. Although the bcc screw dislocations are well known t…
Modality of Equilibration in Non-equilibrium Systems
P. Barat, A. Giri, Nilangshu K. Das +2
An open question in the field of non-equilibrium statistical physics is whether there exists a unique way through which non-equilibrium systems equilibrate irrespective of how far…
Statistics of dislocation pinning at localized obstacles
A. Dutta, M. Bhattacharya, P. Barat
Pinning of dislocations at nanosized obstacles like precipitates, voids and bubbles, is a crucial mechanism in the context of phenomena like hardening and creep. The interaction be…
