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 dissip...ation 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.
