Hosted by the University at Buffalo Department of Mechanical and Aerospace Engineering (MAE), this machine is rated at 55 kips axial force over a displacement range of +/- 2.5 inches. The associated MTS Flex-Test controller and host computer provide for a wide variety of loading functions and data capture options. The machine is located in 618 Furnas Hall and is maintained on a regular basis by technical staff of the MAE department and by MTS field service engineers.
