摘要：
The effect of a small crack on the SIF at the tip of a neighbouring main crack is studied using the finite element method. Both collinear and stacked parallel arrangements are examined. Two extreme orientations of cracks with respect to the interface are considered. Very good agreement is obtained with the available analytical solution in the case of an edge crack. The collinear arrangement magnifies the severity of the main crack. However, the stacked parallel arrangement sometimes leads to a shielding.
