Abstract: The present study is an attempt to take an overview of the work done in the area of bonded repair of plates with composite patches. It was found that since, last decade repair through composite patches is proven to be a very promising technique over other repair methods. This technique improves the fatigue behavior and reduces repair downtime with effective crack retardation. Most of the researchers have done both experimental as well as finite element analysis of bonded repair with composite patches. They had targeted thick plates with plain strain condition and found out stress intensity factor as a measure of fracture toughness. But looking to the large area of applications of thin sheets, it was found that there is a need to analyses bonded repair of thin sheets with composite patches. Care should to taken to minimize the out of plane loading for thin sheets.
