Computational Crack Path Prediction Applied to Crack Arrestability by a Circular Hole
A computational scheme has been developed for the crack path prediction, which is performed by the step-by-step stress analysis ahead of the crack tip and the prediction of a curved icrement of the crack growth by the use of analytically expressed crack path in the neighbourhood of the crack tip. In this paper we consider the cases, where an edge crack in a plate has been initiated under tension and is approaching a circular hole. The present computational crack path prediction is applied to examine the crack arrestability by the hole. Crack paths observed in the corresponding experiments are found to be in good agreement with the computational predictions.
