On the Bearing Failure of Laminated Composite Pin‐Loaded Joints: Exploitation of Semi‐Analytical Solutions for the Determination of the Stress State

Abstract: The present work deals with the development and verification of a set of analytical solutions for the bearing failure of single lap composite joints, which are applied on a composite joint tested experimentally. The stress field originating from the solution is calculated and progressive failure criteria are applied, verifying their applicability as a fast way of calculating bearing failure of a joint. Additionally, the extracted stress field from the results is introduced as a load to the finite element model of the joint under evaluation, and the equivalency of this method is compared and proven against typical implicit non‐linear contact analysis. The major advantage of the proposed methodology is that the highly non‐linear contact problem is circumvented using the stress distribution at the hole boundary as an actual load and thus transforming the analysis to a linear one, providing considerable agreement to the exact high‐cost numerical solution.
