WebMar 12, 2024 · Abstract. A 3D finite element analysis has been carried out to estimate the damage evolution in the CFRP adherend joined using hybrid joint under tensile loading. The load versus displacement behavior of bonded, bolted, and the hybrid joint is compared. Further, damage growth in the CFRP laminate joined using the bolted and the hybrid … Webbolted connections are associated with different structural behaviours. In the mechanical model, single-bolt connections are considered as pin joints, while multi-bolt connections are regarded as semi-rigid connec-tions. In FEM modelling, two developed methods, namely 3D model-ling method and simplified modelling method, are usually employed. devin ratray height and weight https://prioryphotographyni.com
