Concrete Fracture Mechanics
This chapter briefly reviews the basic concepts of concrete fracture mechanics. Linear elastic fracture mechanics (LEFM) studies the stress and deformation distribution in the region in front of a crack tip of brittle materials. It uses a single parameter as an index of the fracture criterion. Two criteria are used in LEFM: one is stress‐based and the other energy‐based. According to the elastic stress field solutions, a stress singularity exists at the tip of an elastic crack. However, in practice, materials tend to exhibit a yield stress, above which they deform plastically. The crack tip opening displacement is the displacement at the point of the crack tip. To study fracture progress in concrete, uniaxial tension tests have been carried out with monitoring of the microcrack occurrence using acoustic emission technique. The best available fracture model for concrete is the cohesive crack of the fictitious crack model pioneered by Hillerborg.
