This rivet installation is an example of the multiple deforming body capability of DEFORM, which was first published in 1994.  While the analysis of multiple bodies during small deflection is possible with some general purpose codes, large deformation of multiple plastic bodies requires a very powerful analysis capability with a sophisticated contact algorithm to generate accurate results.  This simulation is indicative of advanced DEFORM capabilities that are frequently used by fastener manufacturers and their customers.

Over the years, a wide range of 3D mechanical joining simulations have been presented and published.  The installation of staked and self-clinching fasteners are other frequent targets of DEFORM simulation.
