Stress Intensity Factors of a Central Interface Crack in a Bonded Finite Plate and Periodic Interface Cracks Under Arbitrary Material Combinations

Although a lot of interface crack problems were previously treated, few solutions are available under arbitrary material combinations. This chapter deals with a central interface crack in a bonded finite plate and periodic interface cracks. Then, the effects of material combination and relative crack length on the stress intensity factors are discussed. A useful method to calculate the stress intensity factor of interface crack is presented with focusing on the stress at the crack tip calculated by the finite element method.
