The finite element analysis of composite bolted joints requires a trade-off between the precision of the results and the simulation time. In fact, the proper analysis of a composite bolted joint involves the understanding of different linear and nonlinear phenomena. In this regard, the composite bolted joint element (CBJE) is a simplified modeling technique that can be used within a pre-existing shell model. It is made of basic finite elements featuring elastic properties analytically evaluated from the theoretical reference model of bolted joint. These characteristics allow to bring together the exactness of results and the speed of the simulation process. Here, the suitability of the CBJE for the modeling of single-lap multi-column composite bolted joints is assessed. Outcomes of stiffness prediction and bolt-loads distribution are compared with a refined 3D model.

Abstract

The finite element analysis of composite bolted joints requires a trade-off between the precision of the results and the simulation time. In fact, the proper analysis of a composite bolted joint involves the understanding of different linear and nonlinear phenomena. In this regard, the composite bolted joint element (CBJE) is a simplified modeling technique that can be used within a pre-existing shell model. It is made of basic finite elements featuring elastic properties analytically evaluated from the theoretical reference model of bolted joint. These characteristics allow to bring together the exactness of results and the speed of the simulation process. Here, the suitability of the CBJE for the modeling of single-lap multi-column composite bolted joints is assessed. Outcomes of stiffness prediction and bolt-loads distribution are compared with a refined 3D model.
