Finite-width adiabatic shear banding and dislocation patterning in mesoscale polycrystalline aggregates
Siddharth Singh, Rajat Arora, Janith Wanni +6
Dynamic shear banding under adiabatic conditions in a mesoscale polycrystalline aggregate is studied using a model of mesoscale dislocation mechanics and experiments. The model inv…

Field Dislocation Mechanics, Conservation of Burgers vector, and the augmented Peierls model of dislocation dynamics
Amit Acharya
Dissipative models for the quasi-static and dynamic response due to slip in an elastic body containing a single slip plane of vanishing thickness are developed. Discrete dislocatio…

A finite deformation theory of dislocation thermomechanics
Gabriel Dante Lima-Chaves, Amit Acharya, Manas Vijay Upadhyay
A geometrically nonlinear theory for field dislocation thermomechanics based entirely on measurable state variables is proposed. Instead of starting from an ordering-dependent mult…
