Abstract
The present paper aimed to study the effect of the hole on the stress distribution and stress intensity factor of the mode I fracture in a perforated plate with an edge crack. For this purpose, a plate with an edge crack and one or two holes near the crack tip is investigated. First, the cracked plate without a hole was analysed with Abaqus software, and the results were validated through Westergaard’s analytical method. Then, a plate with an edge crack and one or two holes near the crack tip was also analysed with Abaqus software. The effects of the distance between the hole and the crack tip, as well as the radii of the holes on the stress distribution σy and stress intensity factor KI were also investigated. The findings indicated that making a hole in the plate significantly reduces the amounts of the stress and stress intensity factor at the crack tip if the hole has an appropriate radius and position relative to the crack tip.
