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

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

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

A method is described for determining the fracture toughness of plain concrete from three-point bend specimens which accounts for the pre-peak crack growth that occurs upon loading. The fracture toughness so determined is shown not to depend on the size and geometry of the test specimen but on the m
