Distinct Microstructural Characteristic Lengths Defining Notch Fatigue Crack Initiation and Propagation, and Defect Tolerance in Advanced Steels

Advanced Engineering Materials, EarlyView.
Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

Performance Characteristics of Steel Cutting Discs with a Modified Surface for Cutting Brittle Non-Metallic Materials

Механика машин, механизмов и материалов, 2017
The paper is devoted to the experimental estimation of the effect of electroerosive modification of the smooth surface of a steel (U8A) cutting disc on its operational parameters when cutting glass samples using free abrasive, in particular, on the ...

Effect of stacking sequence and geometric scaling on the brittleness number of glass fiber composite laminate with stress raiser

Science and Engineering of Composite Materials, 2014
The fracture behavior of quasi-brittle material exhibits commonly brittle behavior with some ductility in the fracture processing zone. Therefore, a matrix of experimental works is performed to investigate the failure behaviors based on a parameter known

Experimental conditions affecting the measured fracture toughness at the microscale: Notch geometry and crack extension measurement

Materials & Design, 2020
Experimental fracture mechanics at the microscale became an indispensable tool for understanding and developing advanced material systems. In case of linear elastic fracture mechanics, stringent requirements are typically only warranted for very brittle ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

Advanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Investigation of mechanical behaviour of a quasi-brittle material using Karagozian and Case concrete (KCC) model

Journal of Rock Mechanics and Geotechnical Engineering, 2019
The mechanical behaviour of a quasi-brittle material, i.e. Pietra Serena sandstone, was investigated both numerically and experimentally in order to build a reliable numerical modelling system applicable to more complex cases.

The Breaking of Brittle Materials

Physics, 2013
A model shows that as the size of a brittle material grows, the probability that it will fracture from a single crack approaches 100%.
