Abstract
The plane problem of a crack that terminates perpendicularly to a bimaterial interface was re-examined both theoretically and experimentally. Using the complex variable method, the crack trip stress singularities and stress distributions were generalized. Digital photelastic technique was successfully employed to confirm the generalization of the theoretical analysis. The results showed that the so-called far-field effects indeed played a significant role in the stress distribution and determination of the stress intensity factor.
