Annotation: The problem of elastic interaction between cracked plate and the wide anisotropic (composite) repair patch, bonded via rivets and (or) adhesive, and also the problem of calculation of the cracked two-layer riveted and adhesive bonded panel is solved by means of the integral equations method. The computed stress intensity factor are used to predict the crack propagation under cyclic loading. The rate and duration of fatigue crack growth depending on junction type of plates is investigated.
