Mechanisms of tensile fracture of concrete are described. A model is developed for an idealized material. The amount of simultaneous cracking and the path of each crack depend on the rate of stressing. The fracture energy and the tensile strength have been determined as functions of the rate of load
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
