Pulse Peak Delay-Total Focusing Method for Ultrasonic Tomography on Concrete Structure [PDF]

open access: yesApplied Sciences, 2021
An ultrasonic array device like the A1040 MIRA is used to non-destructively visualize the inside of concrete structures. A data set acquired by the ultrasonic array device is so unfocused that an image reconstruction algorithm is required to transform ...

Optimal Design of Sparse Matrix Phased Array Using Simulated Annealing for Volumetric Ultrasonic Imaging with Total Focusing Method [PDF]

open access: yesSensors
The total focusing method (TFM) is often considered to be the ‘gold standard’ for ultrasonic imaging in the field of nondestructive testing. The use of matrix phased arrays as probes allows for high-resolution volumetric TFM imaging.

Enhanced Near-Surface Flaw Detection in Additively Manufactured Metal Ti-5Al-5V-5Mo-3Cr Using the Total Focusing Method [PDF]

open access: yesSensors
Additive manufacturing (AM) enables the fabrication of complex components with high geometric freedom, but it can introduce near-surface flaws due to rapid solidification, resulting in porosity and lack of fusion. In addition, localized melting and steep

Total Focusing Method Based Ultrasonic Phased Array Imaging in Thick Structures [PDF]

open access: yesJournal of Nondestructive Evaluation, Diagnostics and Prognostics of Engineering Systems, 2021
Abstract Ultrasonic non-destructive testing traditionally uses a conventional monolithic transducer. An approach similar to this comprising of independent single transmissions but with reception performed by all the elements in phased array ultrasonics is known as Full Matrix Capture (FMC).

Deep Learning Based Inversion of Locally Anisotropic Weld Properties from Ultrasonic Array Data

open access: yesApplied Sciences, 2022
The ability to reliably detect and characterise defects embedded in austenitic steel welds depends on prior knowledge of microstructural descriptors, such as the orientations of the weld’s locally anisotropic grain structure.
