The challenge that will be posed to researchers for an even longer period is
the development of a predictable model for describing mechanical connections, their
variable stiffness and dissipative contact interaction processes. The main challenge to this
goal lies in the lack of understanding of how friction behaves on a small scale. Coulomb
friction, a large heuristic model is not predictable and has actually been proven to be
untrue in many modes. Expecting a universal law of friction for all types of materials and
therefore contact interactions is not very realistic. Instead, the goal of the international
research community is to develop a predictable model for a limited range of cases. So far,
the metal-metal contact is most often tested, respectively the contact interaction behaviour
of aluminium and steel elements of different quality. We also know that in the application
those two metals are most often found in making mechanical connections. The aim of this
paper is to... make a brief overview of some of the previous tests and approaches to the study
of contact interaction in mechanical connections and the role of friction in energy
dissipation.
