Enhancing the Chemical Reactivity of Graphene through Substrate Engineering

Small, Volume 22, Issue 25, 4 May 2026.
This review highlights methods to enhance the reactivity of graphene through substrate engineering, focusing on strain and charge doping. Strains induced by nanoparticles, metal crystal orientations, or stretchable polymers increase the reactivity of graphene.

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 ...

Effect of Matrix Properties on Quasi‐Static and Fatigue Properties of Thermosetting Polyurethane and Its GFRP Composites

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1929-1943, May 2026.
ABSTRACT In this study, the influence of resin cross‐link density on thermomechanical properties and fatigue behavior of polyurethane resins and glass fiber‐reinforced polyurethane (PUR‐GFRP) composites was investigated. This material is a candidate for renewable energy applications like rotor blades in wind turbines.

The relationship between observed fatigue damage and life estimation models [PDF]

Observations of the surface of laboratory specimens subjected to axial and torsional fatigue loadings has resulted in the identification of three damage fatigue phenomena: crack nucleation, shear crack growth, and tensile crack growth.

Novel Uniaxial and Biaxial Tensile Test Specimen for Polymer Materials

The geometry of the uniaxial tensile test specimen for polymer materials and the testing procedure are defned by the ISO norms. Depending on the type of polymer material, two types of norms are specifed: ISO 37 for rubber-like polymers and ISO 527 for more rigid polymer materials.
