Abstract:The effects of the hole-perpendicularity error on the inter-laminar stress and the mechanical performance of the joint are investigated.It is found that the stress distribution around the hole is heavily affected by the mentioned error.The bolt's posture may adjust when it is fastened in a bolt hole with perpendicularity error,during which the bolt shank bearing the hole wall plays an important role.Moreover,the inter-laminar shear stress increases with the increasing of hole perpendicularity error,which is the main reason for inducing delamination failure.Finally,to increase the fastening torque can help to reduce the negative effects caused by hole perpendicularity error,which was proved by the experimental results.
