AB  - Problems involving contact are of great importance in industry related to
mechanical and civil engineering, but also in biomechanics and other applications. The
contact interaction between surfaces in a bolted splice connection joint or area through
which tire interacts with the road is not known a priori, leading to a nonlinear boundary
value problem. Due to the rapid improvement of modern computer technology, today one
can apply the tools of computational mechanics to analyze contact problems with limited
accuracy, depending on design requirements. However, even now most of the standard
finite element software is not fully capable of solving contact problems, including friction,
using robust algorithms. The aim of this paper is to present some basic concepts of Contact
Mechanics. To illustrate the difficulties arising in computational contact mechanics,
Newton-Raphson scheme was used to solve simple 1D contact problem using penalty
method.

AB  - This paper presents the finite element modeling of bolted joints for structural
dynamic analysis to achieve a reasonable accuracy in simulation results. Non-linear
effects in splice connected joints involve normal compressive loads holding components
together combined with dynamic lateral loads inducing some amount of shear slip in
contact interaction between elements of splice connection joint. The complexities of the
slip process are responsible for the nonlinear nature of the interfaces, both in terms of
stiffness and dissipation. Exploring the physics of joints directly is not readily done
because key interactions takes place at the interface of surfaces, where instrumentation
cannot be placed without changing the problem. Consequences of the specific conditions
of joint connections are increased dynamic problems related to vibrations and dissipative
processes in structure connection joints. Structural joints are the main reason for the
significant level of energy dissipation and source of structural damping. The aim of this
paper is to present some problems regarding research of structural damping and the
importance of study Contact Mechanics to better understand the problem of structural
damping.

AB  - 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.
