Abstract:
The main objective of this paper is to investigate the benefits of Z-fibre
pinning to improve the bonding strength of composite joints. The problem is
addressed from a design point of view in order to develop a simulation
methodology that can be employed to predict the strength of Z-fibre pinned
joints. Firstly, an efficient and accurate computational approach is presented
using the well established finite element method in conjunction with a
constitutive model of Z-fibre response behaviour under mixed mode loading
condition. The Z-fibre bridging model previously developed by the authors is
summarised in the paper. Secondly, the computational approach is demonstrated
via the analysis of two structural joints, namely a conventional T-joint and a
novel cruciform joint. Comparison with test data confirms the model’s predictive
capabilit
