Symposium KK: Dislocation Plasticity

Dislocation Plasticity

The mechanical behavior of crystalline materials is largely determined by dislocations and their interactions among themselves and with other crystal defects. The complexity of these interactions and the variety of collective effects emerging from them keep dislocation mechanics one of the most active fields of research in the mechanics of materials. Recent progress in experimental characterization, together with improved simulation methods and theoretical advances on various scales, established new fields of research (like small-scale plasticity) and stimulated the reconsideration of open questions in dislocation mechanics, such as dislocation patterning and work hardening. This symposium will bring together a broad range of materials scientists for a technical exchange and a discussion of the challenging issues driving research in this field.

Topics will include (but will not be limited to):

  • Structure and energy of dislocations
  • Atomistic simulations of dislocations and dislocation-defect interactions
  • Dislocation dynamics simulations
  • Dislocation-interface interactions (e.g., grain boundaries, twin boundaries, free surfaces, etc.)
  • Dislocation evolution under mechanical deformation
  • Dislocation-controlled damage and fracture
  • Experimental characterization of dislocations
  • Experimental characterization of plasticity
  • Statistical properties of dislocations
  • Nonlinear dynamics of dislocations and pattern formation
  • Continuum modeling of dislocations and plasticity
  • Novel experimental and theoretical techniques for defect and microstructure characterization

Invited speakers include:

Amit Acharya (Carnegie Mellon Univ.), Amine Benzerga (Texas A&M Univ.), William Curtin (EPFL, Lausanne, Switzerland), Gerhard Dehm (Max-Planck-Inst. fuer Eisenforschung, Germany), Benoit Devincre (ONERA, France), Anter El-Azab (Purdue Univ.), Istvan Groma (Eotvos Lorand Univ., Hungary), Marisol Koslowsky (Purdue Univ.), Jeff Kysar (Columbia Univ.), Ben Larson (Oak Ridge National Lab), Michael J. Mills (Ohio State Univ.), Tony Rollett (Carnegie Mellon Univ.), Michael Uchic (Air Force Research Lab), Daniel Weygand (Karlsruhe Inst. of Technology, Germany), Michael Zaiser (Friedrich-Alexander-Univ., Germany).
