Abstract: A number of different high performance cementitious materials have been recently developed.
One class of materials is fibre reinforced cementitious composites (FRCCs). In this study we present a computational two-scale approach to model FRCCs. The main focus is on the discrete fibre distribution on the meso-scale. In our model fibres are added to a continuum damage model in a discrete way, and their influence is taken into account by super-imposing pull-out forces on the matrix material. These fibre pull-out forces represent the link between meso- and micro-scale and are described by an analytical micro-mechanical based model.
Computational efficiency is enhanced since the fibres are not explicitly modelled.
