Özet
In this study, behaviour of hi-adhesive used in the repair of damaged parts was analyzed, using the finite element method. In a double-strap joint with an embedded patch, patch is embedded into the adherents for structural requirements. In addition, to increase the strength of the joint, two adhesives are used to bond the adherents. This approach reduces stress concentration at the overlap ends, ad capacity and delays the failure. These effects give rise to strength. For this purpose, a stiff adhesive, FM73 produced by Cytec Fiberite. was applied in the middle portion of the overlap, while a softer adhesive, SBT9211 from 3M, was applied towards the edges, prone to stress concentrations. Non-linear finite element analyses were carried out to predict the failure loads, to assist with the geometric design and to identify effective ratios of sizes to maximize joint strength.
