Problems on circular-arc cracks between dissimilar materials under antiplane concentrated forces

This paper deals with the problems of circular-arc crack between bonded dissimilar materials under antiplane concentrated forces. By applying the analytic continuation technique and the analyzing method of the Singularity in complex functions, we obtain universal solutions for the problems. For several typical cases the closed form solutions are obtained and the stress intensity factors are devived From these solutions, we provide a series of particular results, some of which coincide with those in Ref.(7).
