We would like to comment on the conclusions made by Gj~rv, S~rensen and Arnesen regarding the notch sensitivity of concrete and the applicability of linear fracture mechanics to small sized concrete specimens.
Analytical modeling and experimental testing are used to evaluate the fracture toughness of plain concrete. The analytical modeling of the fracture toughness considers both the opening of the crack due to the applied external loads and the closing of the crack due to the interlock pressure of the ag
So far, few experiments to determine fracture toughness of autoclaved aerated concrete have been reported in the literature. Tests on three different types of autoclaved aerated concrete using six different specimen geometries have been carried out. Four of the six specimen geometries chosen lead to
When subjected to tensile loads, concrete failure often initiates at the interfacial defects between the mortar and coarse aggregates. The branching of an interfacial crack into the mortar may form a dominant crack which leads to the eventual fracture plane. A simplified model, accounting approximat
