Experimental analysis on the strength of press fit and adhesively bonded axisymmetric components

Press-fit and adhesively bonded joints (Hybrid Joints) are increasingly used as alternative ways of traditional structural joining technique. The main achievable benefits could be summarized in the possibility of maximizing the load transfer (torque or axial) and of reducing both the weight and the stress field of the components, by taking advantages from the adhesive strength. Several hybrid joints characterizations could be found in technical literature on steel-steel components (Steel Hybrid Joints). The aim of this paper is to provide some relevant information on static and fatigue strength properties in case of steel-aluminium components (Mixed Hybrid Joints), by means of experimental tests performed on high strength single component adhesive, which cures anaerobically.
