Ultrasonic NDE in Thick Laminated Composites
Friday, April 22, 1994 4:00 p.m. Dr. Corinne M. Darvennes Department of Mechanical Engineering Tennessee Technological University Delamination sizing in thick composites using ultrasonic techniques is a challenging problem. High frequency waves are needed to provide a sharp image of the defects, but they are attenuated rapidly and do not provide a reliable defect estimate.…
