President, Wyoming Test Fixtures Inc. Fiber-reinforced composite structures are designed with fibers positioned to carry tensile loads in desired in-plane orientations, so why is interlaminar tensile ...

Regardless of the type of mechanical test being performed on composite materials, load introduction into the test specimen is among the biggest challenges. Fiber-reinforced composites have relatively ...

The accuracy and quality of results depends considerably on the cuts made to prepare a sample for tensile testing. It is very important to prepare a sample without nicks or jagged edges for accurate ...

Extensometry is the science of the measurement and analysis of changes in a materials linear dimensions during tensile testing. An extensometer is an instrument that measures test specimen elongation ...

The CIEST Laboratory successfully completed testing pipe liner samples for “apparent hoop tensile strength” as described in ASTM D2290. The method uses a split disk to apply tensile forces to a hoop ...

As the demands for light-weight composite structures for aerospace, ground transportation, and environmentally sustainable energy systems develop, so do the mechanical testing requirements for ...

A four-year IAEA project involving nine research institutes resulted in the preparation of a set of guidelines aimed at standardizing small specimen test techniques (SSTT) for reference structural ...

A neck is formed in a tensile test specimen when the UTS of the engineering stress/strain curve is reached. Prior to this stress-strain condition the plastic deformation occurs throughout the sample ...

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, ...
