Defect reconstruction by non-destructive testing with laser induced ultrasonic detection

Selim, Hossam; Delgado-Prieto, Miguel; Trull, Jose; Picó Vila, Rubén; Romeral, Luis; Cojocaru, Crina (Elsevier, 2020-02)

[EN] This work envisages a detailed study of two-dimensional defect localization and reconstruction, using laser generated ultrasound and its application as a remotely controlled non-destructive testing method. As an ...
Directional Ultrasound Source for Solid Materials Inspection: Diffraction Management in a Metallic Phononic Crystal

Selim, Hossam; Picó Vila, Rubén; Trull, Jose; Delgado Prieto, Miguel; Cojocaru, Crina (MDPI AG, 2020-11)

[EN] In this work, we numerically investigate the diffraction management of longitudinal elastic waves propagating in a two-dimensional metallic phononic crystal. We demonstrate that this structure acts as an "ultrasonic ...
