Abstract

A numerical finite element analysis of the influence of a disturbance: an inclusion or a hole on the stress intensity factor at the tip of an edge crack in a three-point bend specimen is presented. The effect of four parameters is considered: the crack length, the disturbance size and its distance from the crack tip, and the original neutral axis. It is found that both disturbances have an inverse effect on the stress intensity factor: the hole increases it, whereas the inclusion causes it to decrease. The magnitude of the effect depends on the above-mentioned parameters. The numerical results are found to be in good agreement with preliminary experimental findings.
