The feasibility of ranking material fracture toughness by ultrasonic attenuation measurements [PDF]

open access: yes
A preliminary study was conducted to assess the feasibility of ultrasonically ranking material fracture toughness. Specimens of two grades of maraging steel for which fracture toughness values were measured were subjected to ultrasonic probing. The slope

Indentation toughness of Al2O3-CNT nanocomposites [PDF]

open access: yes, 2011
In the last few years new ceramic/carbon nanotube composites have been developed and a number of authors have reported improved mechanical and functional properties in the case of ceramic/CNT composites compared to the monolithic materials.

Strain based design considerations for spiral welded pipelines [PDF]

open access: yes, 2012
Pipelines are constructed in hostile environments where the occurrence of imposed plastic deformations can necessitate a strain based design approach. Under such conditions not only the strength and toughness properties have to be considered; also the ...

Investigation of fiber bridging in double cantilever beam specimens [PDF]

open access: yes
The possibility to eliminate fiber bridging or at least to reduce it, and to evaluate an alternative approach for determination of in situ mode 7 fracture toughness values of composite matrix materials were investigated.
