| Abstract Scope |
NCAL is actively developing several multi-directional testing machines: a 500 kN combined Marciniak/Nakajima punch, a 500 kN cruciform testing frame, a high strain rate tensile frame capable of strains on the order of 100/s, a sheet tension/compression fixture, and a mode II shear fixture. Staff at NIST Center for Neutron Research (NCNR) have developed 2 additional multi-directional testing machines: a shear fixture capable of simple shear and pure shear, and an 'octostrain' testing frame with 8 arms instead of the 4 used for traditional cruciform sample.
This talk will share some of the capabilities of each of these machines, finite element based sample optimization efforts, and the additional instrumentation of digital image correlation (DIC), thermal imaging and diffraction based stress measurements that are available at NIST. As our staff focus on continuous development of these tests, we encourage collaboration to use these systems. |
