Fatigue &Fracture of Engineering Materials &Structures, Volume 46, Issue 11, Page 4103-4118, November 2023., 2023 Abstract The current work investigates the relationship between the crack growth rate (CGR) and the cyclic crack‐tip opening displacement (ΔCTOD) of microstructurally small fatigue cracks by using high‐resolution digital image correlation (DIC). Load‐controlled fatigue tests were conducted on small‐scale specimens of 18%Cr body‐centered cubic ferritic ...

Fatigue &Fracture of Engineering Materials &Structures, Volume 46, Issue 10, Page 3912-3926, October 2023., 2023 Abstract The effects of mechanical and microstructural anisotropy on short fatigue crack initiation and propagation behaviors of a directionally solidified superalloy have been studied. An unusual result was found where the fatigue lives of specimens with grains longitudinally aligned along the loading direction fail at lower lifetimes than specimens ...

Dislocation toughening in single‐crystal KNbO3
Journal of the American Ceramic Society, Volume 106, Issue 7, Page 4371-4381, July 2023., 2023 Abstract The growing research interest in dislocation‐tuned functionality in ceramics is evident, with the most recent proofs‐of‐concept for enhanced ferroelectric properties, electrical conductivity, and superconductivity via dislocations. In this work, we focus on dislocation‐tuned mechanical properties and demonstrate that, by engineering high ...

Influence of Material Thickness on the Ductile Fracture of Steel Plates for Shipbuilding
Polish Maritime Research, 2022 In the shipbuilding industry, the risk of brittle fractures is relatively high because some units operate in arctic or subarctic zones and use high thickness (up to 100 mm) steel plates in their structures.

Fatigue crack growth in notched specimens: a numerical analysis
Fracture and Structural Integrity, 2019 Fatigue crack growth (FCG) is linked to irreversible and non-linear processes happening at the crack tip, which explains different problems observed in the use of da/dN-?K curves. The replacement of ?K by non-linear crack tip parameters, namely the crack

Fatigue Crack Growth in Maraging Steel Obtained by Selective Laser Melting
Applied Sciences, 2019 Selective Laser Melting (SLM) is an additive manufacturing technology, ideal for the production of complex-shaped components. Design against fatigue is fundamental in the presence of cyclic loads, particularly for these materials which typically have ...

Effect of yield stress on fatigue crack growth
Fracture and Structural Integrity, 2019 Fatigue crack growth (FCG) depends on loading, geometry and also material properties. Since FCG is supposedly linked to crack tip plastic deformation, material s yield stress, Y0, is an important parameter.
