An improved 2D finite element model for bolt load distribution analysis of composite multi-bolt single-lap joints

An improved 2D finite element model for bolt load distribution predictions of composite multi-bolt single-lap joints is proposed considering both the efficiency and the accuracy, and this model predicts secondary bending well, which is an important factor for failure of single-lap joints. In this model, the shell element is used to simulate laminates, the fastener technique is used to model bolts, and fasteners are connected to shell elements...
