| Abstract: | In order to improve the knowledge of rivet process,numerical simulation of countersunk head rivet was conducted through FEA.The establishing process of rivet model and big scale deforming of material were introduced in details.The rivet process was divided into six phases according to the stress/time curve.The result shows that numerical simulation can effectively applied to the rivet process and establish the foundation for future analysis of rivet strength and fatigue. |
