In this paper, the issues surrounding the repair of composite structures have been reviewed. This review has highlighted the need for the development of analytical techniques for the design of repair schemes. The finite element method is shown to be an appropriate candidate for such a task. Modelling approaches for adhesively bonded joints are well documented in the literature. Although bonded joints and repair joints share similar features, designing repairs and bonded joints are two different tasks. The open literature on modelling approaches specifically for repair joints is not abundant. Furthermore, there is no evidence of any studies undertaken with the specific aim of looking at the fundamental aspects of applying the finite element method to the analysis of bonded repairs to composite structures. This paper highlights the philosophy behind these modelling approaches that have been used or suggested in the past. These approaches have been compared in order to gain a better understanding of the current state of affairs and how they relate to each other.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
