Multiscale Modeling and Uncertainty Quantification of Heterogeneous Materials
organised by Dr. G. Stefanou
National Technical University of Athens, Greece
and Dr. F. Xu
Stevens Institute of Technology, Hoboken NJ, USA
Session Aims and Scope
Uncertainty inherently exists in measuring/testing, understanding, and modeling of materials across multiple length and/or time scales. Over the last few years, integration of stochastic methods into a multiscale framework or development of multiscale modeling in a stochastic setting for uncertainty quantification (UQ) and reliability analysis of heterogeneous materials is becoming an emerging research frontier. Continuous efforts in this direction are deemed essential to bridge the gap between current "ad hoc" phenomenological reliability models and the multiscale nature of failure mechanisms and damage evolution, typically reflected from intriguing mechanics problems e.g. fatigue, dynamical fracture/fragmentation, earthquake prediction, etc.

The objective of this session is to reflect the recent research efforts and progress towards mingling of multiscale modeling and uncertainty quantification, especially synergistic expertise across continuum/fracture/statistical/quantum mechanics and probability/reliability/stochastic/UQ methods. In this respect, topics of interest include but are not limited to:

  • Concept of Representative Volume Element in elasticity, plasticity, and fracture/damage
  • Strength upscaling of statistical defects at micro- and nano-scale
  • Nonlinear homogenization of random heterogeneous materials
  • Multiple time scale modeling of nonlinear/chaotic dynamics, e.g. molecular dynamics
  • Characterization of random microstructure/morphology
  • Stochastic fracture and damage
  • Wave propagation in random media involving multiple length and time scales
  • Validation of stochastic multiscale modeling techniques
