Symposium description

As substantially demonstrated over the past decades, interfaces play an important role in determining the overall thermodynamic and mechanical response of materials (fatigue, hardening, strength, ductility, fracture toughness, creep, etc.). The understanding and development of predictive capabilities for determining the influence of interfaces on the overall response of a material subjected to a given set of conditions is key for the design of new materials and the optimization of currently used materials. This understanding can only be achieved by taking into account the different length-scales of a microstructure. Therefore, this symposium is dedicated to the studies of interfaces, with a particular emphasis on novel multiscale modeling methods that bridge the gap between material interfaces structure (e.g., geometry, defect content, impurities) and the activation of dissipative processes as well as their role in the generation of internal stresses.

  • Dissipative processes at interfaces: Interface / grain boundary motion and shear coupled grain boundary migration, dislocation – interface interactions, computational thermodynamics of processes driven by interfaces
  • Interface defects and effects on mechanical response and internal state: grain boundary structure, thermodynamics including phase transformations, excess energies, influence of alloying or impurity atoms on localized boundary deformation.
  • Microstructure sensitive continuum methods for interface dominated plasticity: Continuous modeling of grain boundaries and ensembles of grains, higher order models (Cosserat, Strain gradient), phase field approaches. In honor of C. Fressengeas.
