When first introduced to mechanical testing of composite materials, one can be confused, even overwhelmed, by the number of available test standards. One reason for this large variety of tests is the ...

A Standard Test Method is a conclusive procedure that yields a test result. So as to achieve accurate and relevant test results, a standard test method is definite, unambiguous, and experimentally ...

A concern in some practical applications of materials, including composites, is their ability to resist permanent deformation with time under load; to sustain a load when they are deformed by a fixed ...

A material’s hardness relates to its mechanical resistance when subjected to mechanical indentation by another harder body. Diamond is considered the hardest natural material and is typically used for ...

Fission neutrons for materials testing have been available for decades in hundreds of experimental reactors worldwide; an extensive database for irradiated materials is available. Unfortunately, ...

Southwest Research Institute (SwRI) has expanded and advanced a ballistic resistance testing technique, the Laser-Induced Particle Impact Test (LIPIT), previously limited to using microscopic ...
