Theoretical, Experimental and Numerical Advances for Multiscale Deformation and Failure Study in Geo-Materials

Published 04 January, 2023


Description: Geomaterials such as soils and rocks are heterogeneous media composed of complex microstructures, and whose macro-behaviors and failure process are strongly related to their microstructures evolution. Over the past few decades, significant advances in multiscale approaches in geomechanics have been made, particularly in experimental investigation, theoretical development and numerical modeling. A multiscale approach makes it possible to link the microscopic features of the material (microstructure, microphysics and microscopic properties) with the behavior that is observable and measurable at the macroscopic scale. By providing a ‘bridge’ between the scales, modelling could be more predictive and efficient. This mini symposium aims to bring together engineers, and mechanics and computational researchers to discuss ideas and exchange knowledge on the latest developments in the various aspects of multiscale approaches in geomechanics.

Topics covered:

Subject areas include, but are not limited to:

  • Recent development of deep geological repository programs
  • Advanced experimental techniques for investigating deformation and failure behaviors in heterogeneous geomaterials
  • From micro-structural evolutions to macroscopic behaviors
  • Nonlinear and linear homogenization techniques for elasticity, plasticity and damage
  • Advanced numerical methods for full field simulations of heterogeneous geomaterials (elastic deformation, plastic deformation, cracking, etc.)
  • Multiscale modeling of cracking and failure process in structural scale (extended finite element methods, phase field methods, discrete element method etc.)
  • Time-dependent deformation and failure with microstructural evolutions
  • Multiscale approaches for coupled THMC problems
  • Engineering applications and case studies
