Abstract
Swaged bolts are an alternative to high strength (HS) bolts
for connections in steel structures. To clarify the different
steps involved during their specific installation process, a
numerical modelling has been carried out. It allows the
relevant phenomena to be described and to be evaluated. This
numerical calculation accounts for mechanical plasticity and
friction contact between the components of swaged bolts. The
finite element code "Lagamine" designed for the forming
analysis that requires the modelling of the friction between
plastically deformable solids has been used with an original
and quite efficient way to take into account the contact. The
drawing of the stress distributions during and after the
swaging process is the main result of this research.
