Environmental Degradation

  • Chapter
Modeling of Adhesively Bonded Joints

Abstract

Environmental degradation is probably the main on-going concern with regard to the long-term integrity of adhesively bonded structures in-service. This chapter begins by outlining why predictive modelling can make such a valuable contribution in this area and then outlines the steps involved in current state of the art environmental degradation modelling of bonded joints. Essentially, this involves three main steps. The first step is modelling moisture transport through the joint in order to determine the moisture concentration distribution through the joint as a function of time. The second step involves evaluation of the transient mechanical-hygro-thermal stress-strain state resulting from the combined effects of hygro-thermal effects and applied loads. The final step involves incorporation of damage processes in order to model the progressive failure of the joint and hence enable the residual strength or lifetime of a joint to be predicted. The approach adopted here is to outline in summary the key theoretical aspects of each of these steps followed by examples showing how they have been implemented in typical bonded joint finite element (FE) analyses.
