چکیده:

Reliability enhancement of damaged structures through repairs is attracting considerable engineering challenge. Patch repairs to cracked metallic sheets have been accepted as a reliable and suitable technology and offer various advantages. From the available approaches, there are three more common types; adhesive bonded patch, riveted patch and edge welded one. Researchers have extensively investigated the first method, but the two last methods are more common in the industry. In this paper, the analyses of all common various patch connection methods have been performed and compared with each other using FE method. The results have been validated with an analytical method and existing approaches in literature. This investigation shows that adhesive bonded patch has the best performance.
