Multiple Specimen Testing

NIST Inventors

Dave McColskey and Andrew Slifka

Systems and methods are described for concurrently applying loads to multiple test specimens. The systems and methods are useful for cyclical tensile loading of specimens such as in fatigue strength evaluations. The systems and methods are also useful for low frequency cyclical loading evaluations.
