AB  - Driven by the industry's needs to address energy dissipation issues in mechanical connections,
the set goals of the global scientific community, and previous research efforts to interpret how
the condition of contact surfaces between two bodies in contact can be significant, a unique
experimental setup has been devised to study the impact of the state of contact interaction
between two bodies on the system's response. The purpose of the designed experimental setup
is to correlate the roughness of contact surfaces with the deformation of a specially designed
experimental sample. The roughness of contact surfaces represents the most dominant
influencing factor in the contact interaction of two bodies. In terms of scale, the study,
measurement, and analysis of surface roughness fall under the micro and nano scales. On the
other hand, the change in deformation of the experimental sample as a result of the change in
roughness falls under the macro scale. Based on all the aforementioned, the fundamental idea of
the designed experimental setup can be seen. Considering that it is not possible to enter into
contact interaction and explicitly analyse the influence of roughness on the response of a
mechanical connection, the idea in overall research is to consider the macro behaviour of a
specially prepared experimental sample depending on the level of roughness of the contact
interaction surfaces at the micro level. The aim of this paper is to present details and challenges
in the construction of an instrument necessary for such precise examinations, named “Precision
Press with Arcs”.

AB  - The objective of this research is to develop a numerical model of one widely used bolted beam splice connection
that dissipates energy through structural damping. The reference experimental setup is carefully designed to
obtain the highly nonlinear dynamic response due to the suddenly released load. The fact that the monolithic
beam with welded connection has a linear response is utilized for the initial calibration of the numerical and
experimental models. Then, the numerical model of bolted beam splice connection is verified and adopted
through an iterative process. The influences of time and spatial integration, bolt load application, element
type, contact formulation, bulk viscosity, and mass scaling are discussed. A special attention is given to the
load application and load release functions. After the verification, the Abaqus/Explicit numerical model is
validated through the comparison with experimental data, where an appropriate friction coefficient is adopted.
It is demonstrated that the nonlinear structural damping occurs due to the complex micro slip behavior at the
contact interface.
