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. [less ▲]

The recrystallisation model is based on the model developed by Kopp [1,2]. This model is implemented in our finite element code "lagamine" and is coupled with a thermomechanical elasto-visco-plastic law. It assumes that each integration point in the mesh is represented by a number of sub-structures with a different volumic recrystallised fraction. In order to be able to calibrate such a model, we need to perform a lot of experimentals tests. Hot compression tests on small cylinder at different temperatures and strain rates are made till strain level from 0.1 up to 0.7. The compressed cylinders are quenched after the tests. A metallographic study of the quenched cylinders gives the recrystallised fraction function of the strain, the strain rate and temperature. So experimental, numerical and metallographic studies of hot compression tests aim the definition of an accurate predictive thermo-mechanic metallurgical model able to stimulate forging processes.

Hot compression tests at constant strain rate and temperature allow to reach stress-strain curves. These experimental data are then used to calibrate a Norton Hoff elastoviscoplastic model (Gavrus & Massoni 1995). The implementation of this model (Habraken et al. 1997) in the large strain non linear finite element code LAGAMINE is summarised in this paper. Then finite element thermo-mechanical analysis of previous compression tests and independant ones are performed to validate the produced material constitutive model. These simulations give the stress, strain rate and temperature fields of the sample, necessary to predict recrystallisation phenomena. A summary of the recrystallisation models proposed by the literature as well as the simple one implemented in the LAGAMINA code will be presented. So experimental, numerical and metallographic studies of hot compression tests aim the definition of an accurate predictive thermo-mechanic metallurgical model able to simulate forging processes.
