Post-Doctoral Position in Mesoscale Plasticity of Irradiated Alloys

The Materials Theory Group at the School of Materials Engineering of Purdue University has a post-doctoral opening in the area of Mesoscale Plasticity of Irradiated Crystalline Solids.

The postdoc will use discrete and continuum dislocation dynamics to investigate the deformation and fracture of structural alloys for fusion applications. A background in continuum mechanics and crystal plasticity is required for this position. The ideal candidate is one who is strongly interested in the fundamental aspects of deformation and fracture of materials and related computational modeling, and must have excellent programming skills in Fortran and/or C++. The Postdoc will interact with our group members and with our collaborators outside Purdue: Professors Grethe Winther and Henning Poulsen at the Technical University of Denmark who are performing synchrotron measurement of dislocation structures in deformed metals (see related research at

For inquiry about this position, please send an email to Professor Anter El-Azab ( Interested candidates can send a curriculum vita with list of publications, half a page statement of research interests, and the names of two or three references to the email above.

The Materials Theory Group performs theoretical and computational research in the areas of mesoscale plasticity and dislocation dynamics, radiation effects in materials, microstructure evolution, phase field method development, phonon and electron thermal transport in crystalline solids, and computational methods for materials science and mechanics.

All qualified individuals, including diversity candidates are encouraged to apply.

Dislocation Climb in Two-Dimensional Discrete Dislocation Dynamics

In this paper, dislocation climb is incorporated in a two-dimensional discrete dislocation dynamics model. Calculations are carried out for polycrystalline thin films, passivated on one or both surfaces. Climb allows dislocations to escape from dislocation pile-ups and reduces the strain-hardening rate, especially for fully passivated films. Within the framework of this model, climb modifies the dislocation structures that develop during plastic deformation and results in the formation of pile-ups on slip planes that do not contain any dislocation sources.
