Symposium description

Complex porous materials occur both naturally (e.g. clays, shale rocks, and geopolymers) and in engineered materials (e.g. cements, battery electrodes and capacitors, and inorganic membranes). Most recently, the emergence of additive manufacturing has enabled architected porous materials with desirable macroscopic properties. The focus of this symposium is an understanding of the dominant scales in these open materials, their relation to nanoscale properties, and the resultant macroscopic behavior. The symposium will provide a forum for those engaged in experimental, theoretical and numerical characterization of porous, architected materials and non-equilibrium meso-structures. Themes will cover meso-scale structures and their fabrication processes, transport properties, chemoporomechanics, plasticity, creep, and fracture. These properties require the development of new algorithms and application codes for emerging high performance parallel computers and the use of novel imaging techniques such as x-ray synchrotron techniques (3D x-ray diffraction and attenuation tomography and small-angle x-ray scattering) to guide and validate the simulations. The topics to be covered include:

  • Case studies in architected and porous materials, including additively manufactured materials, cement, shale-rocks, electrodes, membranes, …
  • Numerical and experimental characterization of architected and porous materials
  • Integrated modeling and experiment of properties of open meso-scale structures
