Effects of structural defects on strength and fracture properties of multi-walled carbon nanotubes

Nihon Kikai Gakkai ronbunshu, 2017
In this study, we report the relationship between the mechanical properties and structural defects of multi-walled carbon nanotubes (MWCNTs) synthesized by a chemical vapor deposition (CVD) method.

Load‐bearing performance comparison of lap joints in oxide ceramic matrix composites

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract This study evaluates the load‐bearing performance of oxide ceramic matrix composites (Ox‐CMCs) reinforced with continuous fibers, which contain fiber interruptions caused by the manufacturing process. Two different lap joint designs are evaluated: stepped and overlaying lap joints.

Weibull analysis of ceramics and related materials: A review

Heliyon
It has been realized throughout the years that an ideal combination of high toughness, hardness and strength is required in many engineering applications that need load-bearing capabilities. Ceramics and related materials have significant constraints for

Evidence of the most stretchable egg sac silk stalk, of the European spider of the year Meta menardi.

PLoS ONE, 2012
Spider silks display generally strong mechanical properties, even if differences between species and within the same species can be observed. While many different types of silks have been tested, the mechanical properties of stalks of silk taken from the

Microstructural characterization of Ce-TZP/Al2O3 after degradation in water

Journal of Asian Ceramic Societies
In this study, the long-term resistance of Ce-TZP/Al2O3 specimens to hydrothermal treatment is evaluated in terms of their microstructure. Treatment of the specimens is carried out in an autoclave with water at 134°C for up to 360 h. The biaxial strength
