Symposium CT06—Local and Global Fluctuations in Plasticity

Many materials exhibit large fluctuations in their plastic response that, for example, can be a result of abrupt changes in the evolving dislocation network, collective depinning from static or dynamic pinning points, strain localization into shear bands, phase transformations, etc. All of these processes led to spatiotemporal plastic deformation dynamics in a variety of materials, such as pure single and poly crystals, solid solutions, high-entropy alloys, or glassy systems. In this symposium, we seek to discuss the underlying structural mechanisms for strain localization, avalanche dynamics, and intermittent deformation across all length and time-scales of metals or condensed matter in general. We also welcome topics that focus on the evolution of defect populations and how this dictates the macroscopic behavior in response to a thermal or mechanical stimulus. The symposium aims at covering the experimental characterization of these fluctuation phenomenon, novel model development, and also simulations and theory.

The Local and global fluctuations in plasticity symposium brings together a broad range of materials researchers for a technical exchange and a discussion of the scientific issues driving research in this field.

Topics will include:

  • Discrete deformation of crystalline materials across all length scales
  • Shear-band formation and dynamics in metallic glasses
  • Dislocation avalanche dynamics
  • Dislocation network evolution
  • Structural excitations and defect distributions in metallic glasses
  • Intermittency in fracture
  • Serrated flow of high entropy alloys
  • Avalanches in granular and other disordered materials
  • Statistical characterization of intermittent deformation and self-organized critical behavior
  • General theory and microstructural modelling describing avalanche behavior
  • Emerging experimental methods to trace intermittent deformation in single as well as polycrystalline systems
  • Constitutive model development for strain localizing materials
  • Incorporating structural and temporal stochasticity in theories of deformation and failure
