Analysis of Fatigue Life of SPR (Self-Piercing Riveting) Jointed Various Specimens Using FEM

Abstract:

Article Preview

Self-Piercing Riveting(SPR) is becoming an important joining technique for various material sheets and shapes, of automotive application. Fatigue behavior of SPR connections needs to be investigated experimentally and numerically to predict SPR fatigue lives. The simulations of various SPR specimens (Coach-Peel specimen, Cross-Tension specimen, Tensile-Shear specimen, Pure-Shear specimen) are performed to predict the fatigue life of SPR connections under different shape combinations. Finite element models of various SPR specimens are developed using a FEMFAT SPOT SPR pre-processor. The fatigue lives of SPR specimens are predicted using a FEMFAT 4.4e based on the linear finite element analysis.
