Abstract
The influence of a disturbance-an inclusion or a hole, and its relative location on the mode I stress intensity factor (SIF) prevailing at the tip of an edge crack in the three-point bend specimen is determined via the finite element method. Three parameters are considered in the analysis: the crack length, the disturbance distance from the crack tip and the angular orientation of the disturbance with respect to the crack line. In general it is found that the two kinds of disturbances have opposite effects. While, for certain angular locations, the hole induces an increase in the SIF and the inclusion reduces it, for other angular locations the effect of these disturbances is inverse.
