Scanning Acoustic Microscopy (SAM): A Robust Method for Defect Detection during the Manufacturing Process of Ultrasound Probes for Medical Imaging

Sensors, 2019
The main aim of this paper is to provide the feasibility of non-destructive testing (NDT) method, such as scanning acoustic microscopy (SAM), for damage detection in ultrasound (US) probes for medical imaging during the manufacturing process. In a highly

Time of flight fast approximation method for ultrasound sub-surface imaging

Research and Review Journal of Nondestructive Testing, 2023
Time-Of-Flight (TOF) computations are needed in all ultrasound imaging methods. In Non Destructive Testing (NDT), where ultrasound inspections are frequently done using a coupling medium between the transducer and the test piece, wave refraction ...

Increasing the Reuse Potential of High‐Strength Steels by Extending the Fatigue Life through Surface Treatments

steel research international, Volume 97, Issue 8, Page 4326-4336, August 2026.
Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse.

Prediction of Concrete Strength Based on Design Parameters, Hammer Test and Test UPV by Using Artificial Neural Network (ANN).

Journal of Civil Engineering
This study aims to predict the compressive strength of existing concrete without using destructive tests which can damage the surface of the concrete. Destructive testing has the disadvantage of damaging the surface of the concrete, requires a long time

An Ontology-Based Approach to Enable Data-Driven Research in the Field of NDT in Civil Engineering

Remote Sensing, 2021
Although measurement data from the civil engineering sector are an important basis for scientific analyses in the field of non-destructive testing (NDT), there is still no uniform representation of these data.

Nondestructive Testing of Welded Composite Metal Foams

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.

Factors influencing the performance of rebound hammer used for non-destructive testing of concrete members: A review

Case Studies in Construction Materials, 2021
Non-destructive testing (NDT) has a vital role in finding surface hardness of concrete members. B-Proceq curve can calculate the concrete strength by providing statistical correlations between the destructive and the non-destructive strength.
