Symposium description

A major goal of numerical models and computer simulations in materials science is the prediction of the properties as a function of the previous processing or manufacturing of materials. The processing parameters are, however, not state variables of material properties. It is the spatial arrangement of structural elements such as crystal defects, functional domains and chemical constitution that determines the properties of a material - in other words, the microstructure. Simulations of microstructure development provide the state variables for predictions of macroscopic material behavior. In turn, reliable predictions of microstructure evolution require a good understanding and precise modeling or abstraction of the underlying physical mechanisms for microstructure modification. This can be achieved by atomistic simulation of fundamental physical processes and by bottom-up strategies of data transfer to the mesoscopic and macroscopic scales. Additionally, the significant progress in computational thermodynamics and kinetics of materials, through the development of new methodologies at different scales and the coupling with thermodynamic databases, has allowed more realistic and accurate predictions across the different time and length scales. Nevertheless, further progress is still needed, in particular through the development of stronger links between approaches at different scales.

This symposium aims to encourage scientists from diverse areas of materials science and engineering to present and discuss the challenges presented by the modeling and simulation of microstructure and properties development in materials. We welcome approaches in all aspects of materials science that address combined efforts by theoreticians, modelers and experimentalists to understand the microstructure-properties relationship. Possible topics of interest include but are not limited to:

  • Crystal plasticity
  • Microstructure development during phase transitions
  • Microstructure reconstruction
  • Variational methods and homogenization
  • Data analytics in materials science
  • Atomistic approaches
  • Recovery, recrystallization and grain growth
  • Collaborative approaches to materials science by experiments and simulations
  • Experimentally aided Multiscale Materials Modeling
  • Coupling with thermodynamic databases
