Abstract: Major savings in weight can be achieved by tapering laminates away from bolts used in a joint of a composite structure, such as ships and offshore structures. Usually, a three-dimensional (3D) finite element (FE) model is used for the analysis of laminated composite bolted joints as the stresses and strains vary in all directions due to several factors. In case of tapered laminates, it is more complicated due to high out-of-plane displacements and therefore, a 3D FE layered model can usually predict the responses accurately. To overcome this issue, a homogenization scheme is proposed for the simplified 3D FE analysis of such joints. The model can determine the basic mechanical behaviors of a laminated composite joint with significantly lesser computational effort than a layered 3D FE model. The present formulation is based on Mindlin-Reissner plate theory, which takes into account the effect of transverse shear deformation in composite laminates. The proposed model is found to be capable of finding quick and accurate estimation of the basic responses for the composite bolted joints with different tapering configurations in the laminates. ¬© 2019: The Royal Institution of Naval Architects
