Abstract Scope The National Institute of Standards and Technology (NIST) Center for Automotive Lightweighting (NCAL) has developed a novel cruciform testing machine. In addition to the high capacity (500 kN) of the testing frame, each pair of grips can be separately controlled by displacement, force or strain signals. Digital image correlation (DIC) is used to measure full field plastic strain and displacement fields. Thermal imaging is used to track adiabatic heating during deformation. X-ray diffraction is used to map stress tensors in situ during deformation. This presentation will provide an overview of the capabilities of the cruciform testing machine and some of the initial results of our work.
