Polycrystals: Microstructure and Plasticity

 19 - 22 Apr 2022

ICMS, Bayes Centre, Edinburgh

 Enquiries

Organiser(s):

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

About:

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

Important information

We are aware of a very convincing scam targeting participants in mathematical research events. These scammers may telephone or email you and tell you that they are organising accommodation in Edinburgh for you on behalf of ICMS. If you are approached by a third party (eg Business Travel Management) asking for booking or payment details, please ignore. ICMS will never ask you for credit/debit card information.

Programme:

All timings are British Summer Time (BST).
