Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 8, Page 3404-3419, August 2026.ABSTRACT In this study, the fracture response of polypropylene (PP) was assessed using J‐integral evaluation, J‐R curve construction, and fractography examination. J‐R and load–displacement curves were analyzed to determine critical loads and estimate J‐integral values based on standards established for polymer fracture testing, which led to the ...

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