| Résumé : |
Due to the increasing use of composite materials in critical structural applications demanding a high strength-to-weight ratio, reliable evaluation tools are now more than ever necessary. Ultrasound is well known in the field of non-destructive testing and evaluation (NDTetE) and classical ultrasonic C-scan techniques have already proved their usefulness in visualizing defects, delaminations, etc. However, due to their inherent limitations in quantitative characterization, the quest for more sophisticated NDTetE methods to monitor complex damage mechanisms is a significant challenge in current research since one of the most critical degradation mechanisms of composite materials involves fatigue, which is associate with a localized reduction of the material stiffness. The very promising ultrasonic polar scan technique is investigated and discussed in this study. |
