Abstract

A global/local method, or sub-modelling method, has been developed to obtain a fine description of cracking in concrete specimen. A discrete-element model is used to re-analyse at a local scale the damage zone obtained after the finite-element analysis of the global specimen. This strategy is applied to study the influence of size effect on cracking of plain concrete. The numerical results are compared to available experimental results obtained with the Digital Image Correlation method.
