Abstract

Bolted composite joints are the most common forms of connections in engineering structures. A numerical study has been carried out to investigate the tensile stress, shear stress and the bearing stress behavior of a plate containing bolted composite joints. It is necessary to determine stress around the joints in order to determine the site of crack initiation, which can severely reduce the overall strength of the structure. Finite element model for single-lap composite joint consists of eight laminates and bolt. The effect of alignment of fibers with respect to the loading direction on the site of crack initiation of composite bolted joints will be investigated. It can be concluded that, the site of crack initiation depends of fiber orientation. Furthermore, the site of crack initiation is almost interior the plate thickness.
