The objective of this mini-symposium will focus on recent advances, challenges, and on-going research in multiscale computational models for cementitious materials and cementitious composites focusing on characterizing fracture and/or transport processes and their mutual interactions within the context of durability and material design.
Among others, the following topics will be covered by the minisymposium:
• Multiscale and multilevel models for the characterization of concrete and fiber-reinforced cementitious composites
• Multiscale models for fatigue failure of cementitious materials
• Multiscale micromechanics and computational meso-scale models (e.g. Pore-network models, Lattice, CT based FE models) for characterizing damage and/or transport in cementitious materials
• Homogenization and upscaling methods (continuum micromechanics, computational homogenization etc.)
• Novel discretization methods (cohesive zone models, phase-field models, gradient (non-local) damage models, XFEM, peridynamics etc) applied to fracture processes in concrete
• Modeling of transport and physico-chemo-mechanical processes (creep, shrinkage, chemical dissolution, chemically expansive processes)
