Thermomechanical modeling of the metallic rivet in friction riveting of amorphous thermoplastics

Abstract The present work aims for an initial computational simulation with finite element analysis of the friction riveting process. Knowledge and experimental data from AA2024-T351 polyetherimide supported simulation. Friction is a friction-based joining technology capable connecting multiple dissimilar overlapping materials in fast simple manner. In this paper, plastic deformation metallic rivet, process heat input, temperature distribution were modeled simulated. rivet key importance creating mechanical interlocking main mechanism between parts, being focus work. influence polymeric material was considered dynamic boundary condition via input pressure profiles applied to rivet. mainly generated by viscous dissipation within molten polymer, analytically estimated. Three conditions flux values modeling different determined (8.2, 9.1, 10.2 W/mm 2 ). These yielded distinct deformations characterized diameter tip, 5 mm 6.2, 7.0, 9.3 mm. maximum temperatures 365, 395, 438 °C, respectively.
