Abstrakt Abstract:

This work aims at providing a numerical tool for the efficient design of the self piercing rivet by means of finite element simulations. Abaqus standard v 6.7 software has been used to establish a 3D model for simulation of the shearing and peel test on the riveted joint. This is done in order to understand the mechanical strength and failure mechanism of the joint. Shear and tensile tests were performed to compare experimental and numerical results. The numerical model was validated against experimental results. The aim of analyzing the strength of SPR is to predict the fatigue life for SPR joined structures through process optimization. Here we found out that mechanical behavior like strength does not only depend on geometry but also depend on process parameters. The complex riveted joint geometry and its three dimensional nature combine to increase the difficulty of obtaining an overall system of governing equations for predicting the mechanical properties of SPR joints and the experimental predictions are time consuming and expensive. Though using FEM frequently solves the problem.
