Rivet heading – theoretical investigation and experimental verification

Abstract

Determination of stress-strain state in the technology of plasticity is essential as the knowledge of this state enables the determination of basic process parameters such as: deformation force, mean pressure and deformation work. Furthermore, it makes possible the analyse of the potential of material formability. In this paper theoretical and experimental investigation of rivet heading by spherical die is presented. Methods of the analysis: SLAB method and method of work of deformation. Experimental investigation has been carried out in order to verify the theoretical results. Reasonable agreement between theory and experiment has been obtained.
