摘要
In this paper, the stress intensity factors (SIFs) of a single edge interface crack in the bi-material bonded strip subjected to in-plane tension and bending moment are investigated systematically. The SIFs are computed for arbitrary material combinations with varying the relative crack size a/W. Specifically, some necessary skills as refined mesh and extrapolations of the stress intensity factors are used to improve the accuracy of the calculation. For the edge interface crack, it is found that the dimensionless SIFs are not always finite for the edge interface cracks in the bonded semi-infinite plate depending on Dundurs' material composite parameters.
