Calculation of hybrid joints used in modern aerospace structures

Abstract

The state – of - the art of aeronautical structures show that parts are manufactured and subsequently assembled with the use of fasteners and/ or bonding. Adhesive bonding is a key technology to low weight, high fatigue resistance, robustness and an attractive design for cost structures.The paper results resolve significant problems for two groups of end-users:1) for the aerospace design office: a robust procedure for the design of the hybrid joint structural components;2) for the aeronautical repair centres: a useful procedure for structural design and analysis with significant cost savings.
