Fatigue Crack Growth Behavior due to the Localized Compressive Deformation on Structural Steel

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1597-1609, May 2026.
ABSTRACT The localized compressive deformation (LCD) process was used to analyze the fatigue crack growth behavior of a high‐strength low‐alloy structural steel. Eccentrically loaded single‐edge crack tension specimens (ESE(T)) in accordance with standard ASTM E647 were precracked at a crack length of about 4 mm from the machined notch by applying a ...

Transillumination‐Aided Infiltration of MIH‐Affected Molars: Evaluation of the Clinical Workflow

open access: yesInternational Journal of Paediatric Dentistry, Volume 36, Issue 3, Page 412-419, May 2026.
ABSTRACT Background Enamel affected by molar incisor hypomineralisation (MIH) exhibits reduced mechanical properties due to its disorganised prismatic structure, lower mineral density and higher protein content. These alterations increase porosity and susceptibility to posteruptive enamel breakdown.
