摘要：

A brittle fracture criterion for structures with sharp notches is proposed. It is based on Irwin's and Novozhilov's criteria and states that a crack will propagate from a tip of a notch when the actual value of the stress intensity factor K(I,II,III) reaches a critical value. The considerations were carried out within the limits of linear elastic analysis and based on the general expressions for the stress distribution in the vicinity of the notch-tip. The parameters required to estimate the brittle fracture hazard can be easily obtained from experiments.
