An adhesively bonded anisotropic structure containing a part-through crack is analyzed. Two plates are bonded through an adhesive of constant thickness which is treated as a two dimensional shear spring in the analysis. The cracked plate is considered to contain a through-crack of finite length in the direction of fiber.
The problem is reduced to a pair of Fredholm integral equations of the second kind. By solving these equations the interface shear stresses acting on the adhesive, the stress intensity factors, and the in-plane stresses of the cracked plate are calculated.
Numerical results are presented for various fiber angles of composite plates. The results show that mixed-mode stress intensity factors $K_I$ and $K_II$ exist under tension.
Photoelastic coating technique is used to determine the stresses of the cracked plate. Finally, the stresses obtained by photoelastic coating technique are compared with those of the analytical method.
