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
