Determination of CTOD C in Fibre Metal Laminates by ASTM and Schwalbe Methods [PDF]

Materials Research, 2002
Fibre Metal Laminates (FMLs) have arisen as a demand of the aeronautical industry to use thin sheets with high resistance to fatigue crack growth, high damage tolerance, corrosion resistance and high specific strength.

Self‐Cleaning Sensor Surfaces for Long‐Term Environmental Monitoring

Advanced Engineering Materials, EarlyView.
Long‐term use of unattended outdoor sensors without soiling or biofouling is achieved through generation of a micro‐ and nanorough cuvette surface by combing hydrophobic nanoparticles with fluorinated polymers, crosslinked and surface‐attached through CHic chemistry. The coating demonstrates self‐cleaning behavior and prolonged outdoor stability, which

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

Experimental and Numerical Analysis of Fracture in 41Cr4 Steel – Issues of the Stationary Cracks

International Journal of Applied Mechanics and Engineering, 2018
This paper analyzes the process of fracture in 41Cr4 steel on the basis of experimental and numerical data obtained for non-propagating cracks. The author’s previous and latest experimental results were used to determine the apparent crack initiation ...

Controlling Grain Growth in Powder Bed Fusion of Yttria‐Stabilized Zirconia Using Femtosecond Lasers: Challenges and Methodological Insights

Advanced Engineering Materials, EarlyView.
Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

Interfacial crack analysis in layered media using couple-stress elasticity and the displacement discontinuity method

Tạp chí Khoa học và Công nghệ
Interfacial cracks between dissimilar materials represent a critical failure mechanism in layered structural systems such as coatings, composite laminates, and micro-structured materials. However, classical elasticity theory cannot adequately capture the

Creep Fracture Characteristics of Fractured Rock Mass Strengthened with Toughened Epoxy Resin

Advances in Civil Engineering, 2021
For improving the toughness and long-term strength of the fractured rock mass reinforced with epoxy resin and reducing the opening displacement of the crack tip, three types of converging cracks are established according to the deformation and failure ...

Feasibility and Limitations of the Advanced Replica Process for Bioactive Glasses

Advanced Engineering Materials, EarlyView.
Periodic 3D‐printed Kelvin‐cell templates enable a controlled advanced replica process for fabricating highly porous glass lattices. Across P45K9, 45S5, and 13–93, material‐dependent differences in coating, burnout, and shrinkage lead to distinct strut morphologies, while comparable final porosities of 83%–88% are retained.
