Abstract
The simulation of hybrid composite-metal bolted joints using finite element analysis necessitates balancing the accuracy of the results and the simulation time. Accurately analyzing a bolted joint involves understanding various linear and non-linear phenomena. To simplify this process, the Composite Bolted Joint Element (CBJE) technique can be used as a modeling tool within an existing shell model. The CBJE technique uses basic finite elements featuring stiffness characteristics evaluated from the theoretical reference model of the bolted joint to provide precise results in a short time. In this study, the effectiveness of the CBJE technique is examined in the modeling of hybrid double-cover butt joints by comparing the outcomes of stiffness prediction and bolt-load distribution with those generated from a refined 3D model.
