TITLE
Numerical Modelling of Riveted Joint Structures From Riveting Process down to Structural Analysis

ABSTRACT
In this paper we present the main numerical difficulties to model the riveting process: contact between deformable bodies, plastic deformation, damage and sometimes fracture. Forge2® and Forge3® finite element software enable to model large deformation of elastic-plastic materials in 2D and 3D configurations. Some recent developments enable to deal with multi-bodies contact and to model damage and fracture. These developments are used here to model three different riveting processes. After a 2D simulation of the riveting process, it is possible to export the mechanical fields into a 3D mesh and then to perform a 3D shearing test on the riveted structure. In the future this technique can be used to modify the riveting process parameters to optimize the structural resistance of the riveted structure.
