Damage evaluation in composite structures based on image processing of ultrasonic C-scans

Angelika Wronkowicz, Andrzej Katunin


The article presents a method of reconstruction of planar ultrasonic maps into a three-dimensional form based on levels of attenuation of ultrasonic waves through a tested composite structure. A developed algorithm is based on image processing techniques, which allows enhancing ability of interpretation of damage extent at particular depths of a tested structure.
