Symposium description

The purpose of this symposium is to bring researchers together to discuss plasticity modelling and experimental strategies in the area of materials under extreme and ambient environments. In the discussion, both success stories and on-going work will be incorporated. The focus will be on a range of material families and complex plasticity phenomena including (but not limited to):

  • Cyclic deformation and fatigue
  • Hydrogen embrittlement
  • High-temperature materials and creep
  • High-rate deformation, including materials subjected to shock and penetration
  • Crystal plasticity as a tool to interpret the above

The symposium will encompass both simulations and novel experimental techniques. Simulations that directly inform other length and time scales, or improve current multiscale strategies, are essential. Therefore, the symposium will incorporate contributions from atomistic and electronic modelling that inform plasticity modelling. The use of thermodynamic and statistical mechanics concepts to describe plasticity under extreme conditions is also of interest. Crystal plasticity and finite element method strategies addressing the topic areas listed above will be part of this symposium.

Experimental validation and parameterization are an essential part of multiscale materials modelling and such studies are encouraged in this symposium. There is a wide range of novel experimental techniques focused on describing atomic distributions, microstructure and defects at lower scales. These include atom probe tomography, high-resolution transmission electron microscopy and synchrotron radiation. Notably, micro- and nano-pillar deformation have been very useful in describing glide planes, twin formation and deformation; and the roles of impurities. Finally, given the conference theme of "The Microstructural Frontier," studies that focus on microstructural effects are particularly encouraged. For example, the role of microstructure and interface engineering in regard to improving damage tolerance is particularly relevant. Also, contributions aiming at experimentally clarifying the microstructural transitions occurring under extreme conditions are of interest.
