Abstract The fatigue crack growth behaviour of dissimilar bonded materials was studied using explosively bonded naval brass clad steel plate and roll bonded nickel clad and naval brass clad steel plates. When the residual stresses produced during manufacturing processes were small, the fatigue crack growth rates showed a good correlation with the true ΔK-values evaluated for the dissimilar bonded materials; apparent ΔK-values, determined on uniform material, failed to be a correlating variable. The residual stresses strongly affected the fatigue crack growth rate of the dissimilar materials. Some microscopic and fractographic observations were made on the fatigue-fractured dissimilar materials.
