Ultrasonic investigation of the effect of compressive strains on 3D periodic bi-material structures Article dans une revue avec comité de lecture; ;POMAREDE, Pascal; ; PIOTROWSKI, Boris; MERAGHNI, Fodil; (EDP Sciences, 2022-06)
Due to the specific elastic properties such as high stiffness to mass ratio, regular microstructure materials are widely used in the industry. The need for nondestructive evaluation is ubiquitous to ensure material quality. ...
