The failure of concrete has been the subject of much research, but there is still no general failure theory for concrete. The primary purpose of this paper is to present a criterion of failure based on the concept of limiting tensile strains. This work is based partially on ideas presented earlier by Newman, partially on experimental work conducted by the authors, and partially on an analysis and synthesis of the previous work of others. It is limited to states of uniaxial and biaxial loading. The discontinuity point is adopted as the definition of failure, and the experimental results show that a maximum tensile strain criterion holds for failure.
