Finite element modeling of the contact of elements preloaded with a bolt and externally loaded with any force
TL;DR: In the modeling, non-linear phenomena occurring in the contact zone of such elements for both the preloading and operating conditions of the connection were taken into account and the finite element method were used for creating the physical and mathematical models of the bolted connection.

TL;DR: An elastic-plastic finite element model for the frictionless contact of a deformable sphere pressed by a rigid flat is presented in this paper, which provides dimensionless expressions for the contact load, contact area and mean contact pressure, covering a large range of interference values from yielding inception to fully plastic regime of the spherical contact zone.
