Abstract
An experimental and numerical investigation is carried out for a parti cular testing geometry: a single-edge notched specimen subjected to fo ur-point shear, where a mixed-mode crack propagation is activated in c oncrete, if the specimen is not too small and the aggregates are not t oo large. When both conditions are verified each crack growth step is governed locally by a mode I strain field and the energy dissipation i s tendentially provided by the fracture energy G(F), whereas permanent deformation in the bulk material and interlocking on the crack surfac e are negligible.
