Abstract:

A three-dimensional finite element analysis is presented on the effects of bolt-hole clearance in composite bolted joints. Both single bolt and multibolt single shear joints were modelled and the results are compared with those from a parallel experimental programme. The specimens studied were made from graphite-epoxy HTA/6376, with quasi-isotropic layups. Protruding head bolts of 8 mm diameter, torqued to finger tight conditions, were used. The models showed excellent ability to quantify the effects of increasing clearance, which included reduced contact area and overall stiffness in the single bolt case, and substantially changed load distribution in the multibolt case.
