Influence of the assembly process on the shear strength of shaft-hub hybrid joints

Interference fitted and adhesively bonded joints, also known as hybrid joints, are an effective means to increase the transferable load while reducing both the weight and the stress level of the joined components. Many researches evaluated the strength of hybrid joints in dependence of several variables, such as the assembly pressure level, the type of materials in contact, the curing methodology, the operating temperature, and the loading type. To the authors' best knowledge, no data are available about the influence of the assembly technique on the shear strength of hybrid joints. This paper aims at filling the gap, by comparing the shear strength of hybrid joints realized by 'press fitting', by 'shrink fitting' and by 'cryogenic fitting'. (c) 2013 Elsevier Ltd.
