AN INSTABILITY THEORY OF FAILURE FOR CONCRETE

A simple mathematical model is proposed in which the failure of concrete under uniaxial compression is attributed to the instability which develops in the macro-elemental structure formed by cracking. The model predicts that there is a critical fracture length which is, with the ultimate stress, dependent upon factors such as size of specimen and longitudinal stress gradient which have previously only been explained by statistical strength theories. The model predictions are compared with the experimental evidence available. /Author/TRRL/
