Experimental investigations on bonded cylindrical joints

Although bonding as a jointing method for metals has quite a number of advantages, this method so far has had only modest significance in the field of vehicle construction. This rather sceptical view of bonding can be attributed to the lack of appropriate empirical values and calculating standards. Starting from this viewpoint, experimental results are described, which have been elaborated on bonded cylindrical joints under static and dynamic loading as a joint project with Loctite Ireland. Subsequently the practical applicability of these experiments is discussed. The paper describes the following items: reaction to deformation of adhesive coat under axial and torsional loading respectively; dependence of nominal shear strength on load direction; computed interpretation of press fit joints and shrink fit joints with bonding; finite fatigue life and endurance limit of bonded joints in dependence on various influential parameters failing mechanisms of dynamically loaded bonded joints; cyclic softening and hardening effects.
