The two side-by-side values indicate how durable or damage-tolerant the material is, as high values suggest greater toughness.

Fracture toughness was measured using the single edge notched bend (SENB) test. Results showed that by increasing the nanofiber yarn content in the epoxy, the elastic, plastic and the total works as well as the maximum load related to the initiation of crack propagation were improved. Roughness...

if the fracture occurs outside of the area in which the strain is measured, the test results must be thrown out. If using straight-sided pieces, it is a good idea to prepare multiple samples in case this happens.
Now, this might seem like a stupid test. Bikes don't normally fail because tension loads are too high. But the compressive strength of a metal tends to follow its tensile strength quite closely. As a result, tensile strength is a pretty good indicator of how the material will behave in ...
to note is there is no major dropoff in toughness even with 1625°F/880°C austenitizing, which shows that the tungsten and vanadium carbides are effectively “pinning” the grain boundaries and keeping the grain size small even at that relatively high temperature. The fracture grain was also...
Crush test or compressive strength test is a test widely used to determine the strength of concrete bearing loads. Weld fracture test is a test designed to reveal imperfections such as cracking due to inadequate width to height ratio, incomplete penetration, lack of fusion, porosity, and slag in...
Under the assumptions of linear elastic fracture mechanics, the criterion for fracture in mode is , where is a material parameter (calledfracture toughness). In this way, it’s possible to study geometries with this special type of singularity without explicitly using the infinite stresses. This ...
While a lot of work has been done to improve the active and passive behavior of this 1D muscle system in the past, the volumetric muscle system of THUMS was modeled in a much more simplified way based on Post Mortem Human Subject (PMHS) test data. The stiffness changing effect of ...
For testing toughness I austenitized the NJSB-cycled material from 1475°F (to match the NJSB datasheet); the KSN-cycled, AKS-supplied, and Buderus-supplied material from 1525°F; and the Jantz-supplied material from 1580°F. That 1580°F temperature was selected to test the higher recomme...
