Abstract

This paper proposed a detailed three-dimensional finite element model (FEM) for composite mechanical joints and developed a parametric, automatic, and process-based tool for rapid modelling and analysis of such joints. The tool allows for batch modelling and analysis for large configurations, significantly improving simulation efficiency. A signal-bolt, signal-lap composite joint was analysed to demonstrate the effectiveness of this tool. In the simulation, the clearance effect was studied and the reduction in stiffness with the increasing clearance was captured by the model. Based on the neat-fit (C1), the overall stiffness of the C2, C3 and C4 configurations obtained by simulation in this paper are reduced by 1.68%, 3.86% and 9.23% respectively. While the stiffness reduction measured by experiments are 1.90%, 7.30%, and 10.4%, respectively.
