Continuum damage modelling of environmental degradation in joints bonded with EA9321 epoxy adhesive

A mesh independent continuum damage model has been proposed to predict the residual strength of adhesively bonded joints by introducing a displacement-based damage parameter into the constitutive equation of damaged materials. Joints bonded with a ductile adhesive EA9321 were studied for a range of environmental degradation. The moisture dependent damage parameter for EA9321 was calibrated usin...

Reliability analysis of bonded joints with variations in adhesive thickness

Nondestructive Testing for Environment Al Degradation of Adhesive Joints Introduction

The work described here is an uHrasonies based experimental study which aims to address the lack of a reliable technique for detecting strength loss in adhesive joints after exposure to hot wet environments. This is manifested as a change in the failure mode of an adhesive system from a cohesive failure in the as-made condition, that is failure through the adhesive, to an adhesive failure, fail...

Monitoring of Disbonding in Bonded Composite Joints Using Cfbg Sensors Embedded within the Adhesive Bondline

Chirped fibre Bragg grating (CFBG) sensors have been embedded within the adhesive bondline of single-lap bonded composite joints, fabricated using a transparent glass fibre reinforced plastic (GFRP) adherend bonded to a carbon fibre reinforced plastic (CFRP) adherend. During fatigue cycling, disbonds initiated adjacent to the cut ends of one, or both, of the adherends and the disbonds propagate...
