Abstract

This document presents an improved scheme that has been developed to enable the assessment of the moisture uptake in adhesive joints utilising the finite element method. A transient finite element procedure has been applied to accurately predict the moisture concentration within the adhesive layer. This approach can accommodate irregular joint geometries in three dimensions. It offers substantial time savings compared to the previously used analytical approach since the nodal concentration results can be directly transferred to the global FE model and readily linked with the moisture-dependent mechanical properties. Comparison of the finite element and analytical results for a one-dimensional diffusion problem showed excellent correlation.
