A data driven approach for cross-slip modelling in continuum dislocation dynamics
Vignesh Vivekanandan, Ben Anglin, Anter El-Azab
Cross-slip is a thermally activated process by which screw dislocation changes its glide plane to another slip plane sharing the same Burgers vector. The rate at which this process…
A First Experiment at Interfacing Crystal Plasticity and Continuum Dislocation Dynamics
Khaled SharafEldin, Peng Lin, Vignesh Vivekanandan +3
A computational approach has been developed for the analysis of the properties of 3D dislocation substructures generated by the vector density continuum dislocation dynamics (CDD),…
Incorporating point defect generation due to jog formation into the vector density-based continuum dislocation dynamics approach
Peng Lin, Vignesh Vivekanandan, Benjamin Anglin +2
During plastic deformation of crystalline materials, point defects such as vacancies and interstitials are generated by jogs on moving dislocations. A detailed model for jog format…
On the computational solution of vector-density based continuum dislocation dynamics models: a comparison of two plastic distortion and stress update algorithms
Peng Lin, Vignesh Vivekanandan, Kyle Starkey +3
Continuum dislocation dynamics models of mesoscale plasticity consist of dislocation transport-reaction equations coupled with crystal mechanics equations. The coupling between the…
On the implementation of dislocation reactions in continuum dislocation dynamics modeling of mesoscale plasticity
Vignesh Vivekanandan, Peng Lin, Grethe Winther +1
The continuum dislocation dynamics framework for mesoscale plasticity is intended to capture the dislocation density evolution and the deformation of crystals when subjected to mec…
