Integrated GPR and Electrochemical Methods for Monitoring Steel Rebar Corrosion in Reinforced Structure

NDT - Journal of Non-Destructive Testing
Reinforced concrete structures, once considered very durable and capable of withstanding a variety of adverse environmental conditions, often suffer from premature reinforcement corrosion, compromising their safety and serviceability. Ensuring the safety

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.

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.

Non-Destructive Classification of Concrete Moisture Levels Using Piezoelectric Contact Microphones and Impact-Based Acoustic Signals with a Hybrid Stacking Framework: A Controlled Experimental and Theoretical Study

NDT - Journal of Non-Destructive Testing
The long-term durability of concrete structures is significantly affected by moisture. Excessive moisture may cause drying shrinkage, crack formation, and accelerated corrosion of embedded reinforcement; therefore, reliable and non-destructive moisture ...
