Nonlinear ultrasound for nondestructive evaluation of adhesive joints

Résumé

Adhesive bonding technology has gained much attention in many industries, specifically aeronautic. However, to be used for structural joining and critical application, high reliability is needed. Thus, efficient non-destructive control strategy should be proposed to evaluate the nominal bonding quality but also possible progressive in-service degradations. On-going effort has been made to develop methods for cohesive defects detection and adhesion quality assessment. In this paper, we propose a method based on the measurements of nonlinear features of weak bond defects, without any hypotheses of known elements on the adhesive bond (e.g. thickness of the substrates or the adhesive). It is applied to nondestructive testing of metallic substrates joined with thin adhesive (100μm).
