Multiscale framework for modeling of fracture in high performance fiber reinforced cementitious composites

摘要

A sequential multiscale approach is applied to model fracture in high performance fiber reinforced cementitious composites. For each relevant length scale, dominant substructures and associated physical mechanisms of deformation are identified and appropriate analyticalumerical model is formulated. Attention is paid to ensuring proper interconnections between these models. Validation through reproduction of experimental results proves viability of the multiscale approach.
