Polycrystals: Microstructure and Plasticity

 19 - 22 Apr 2022

ICMS, Bayes Centre, Edinburgh


  • John Ball, Heriot-Watt University
  • David Bourne, Heriot-Watt University
  • Myrto Galanopoulou, Heriot-Watt University
  • Lucia Scardia, Heriot-Watt University


The theme of this workshop was the mathematical theory of polycrystalline materials at multiple scales. This interdisciplinary meeting brought together researchers working in elasticity, plasticity, and dislocation theory to understand the effective behaviour of polycrystals and their microstructures.
