Modern Hybrid Joints in Aerospace: Modelling and Testing / Nowoczesne Połaczenia Hybrydowe W Lotnictwie: Modelowanie I Badania Eskperymentalne

Abstract

The aim of the paper is to review different types of modern hybrid joints applied in aerospace. We focused on three particular cases: 1) spot welding - adhesive, 2) rivet-bonded and 3) clinch-bonded joints. The numerical models presented in the paper for these joints describe their complex behaviour under mechanical loading. The numerical calculations performed using ABAQUS code were compared to experimental results obtained by application of the Digital Image Correlation system (DIC) ARAMIS.The results investigated within the paper lead to the following major conclusions:- the strengthening of joints by application of adhesive significantly improve static strength,- the final failure of the joined structural system significantly depends on the surface adhesive area,- the stiffening effects of the hybrid joint lead to higher reliability and durability of the structural joints.
