Prediction of net-tension failure of multi-bolt composite joints: A fast approach for laminates with arbitrary layup

In this study, a new fast approach to predict the net-tension failure strength of multi-bolt composite joints was developed based on finite fracture mechanics and p-version parametric finite element methods. In the proposed approach, stress distribution and stress intensity factor are obtained using the principle of superposition, based on which the problem can be divided into open hole tension and hole bearing problems. The stress distribution...
