Probabilistic estimation of reliable sensor spacing for wire break detection in prestressed concrete using acoustic emission technique

Structural Concrete, EarlyView.
Abstract The acoustic emission (AE) technique has proven to be an effective method for detecting individual wire breaks in prestressed concrete structures affected by stress corrosion cracking (SCC). However, despite its widespread application, the quantitative assessment of AE monitoring reliability and optimal sensor placement remains unresolved ...

Fatigue of AM TiAl6V4: Probabilistic Modelling of the Size Influence as a Transfer Method From Test Specimen to Part

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This paper investigates the fatigue behavior of additively manufactured TiAl6V4 by comparing two specimen geometries with different highly stressed volumes. A fracture mechanical approach based on the El‐Haddad–Smith–Topper model is combined with defect analysis through X‐ray computed tomography.

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.
