Mechanics is an essential part of making and using materials, ranging from metals and ceramics, to functional materials and concrete. The most important aspect of mechanics of materials is the intimate connection with the microstructure and the structural defects, which is termed here mesoscale mechanics of materials. This symposium brings together researchers in the field to discuss mesoscale mechanics in materials science. The topics of the symposium include, but are not limited to, the following areas:

  • Defects and their mechanics in materials
  • Dislocation plasticity
  • Mechanics of creep, fatigue and fracture
  • Microstructure mechanics and role of mechanics in phase changes in materials
  • Experimental characterization of stresses and deformation fields at the mesoscale
  • Theoretical, computational and experimental multiscale concepts in mechanics of materials
