Abstract: An experimental method for testing the cyclic adhesive properties of polymer coatings bonded to a metal substrate was created. The goal of this work is to more accurately predict the behavior of blisters formed on the hull of a seagoing vessel and their propagation behavior under cyclic or fatigue loading conditions. In this first phase of the experimentation, the work of other researchers was reviewed as well as completion of a preliminary model of the tested specimens and an analysis of the data obtained from testing in a lab air environment for a single strip blister specimen. The fatigue loading used an R value of 0.3.
