The MTS 100 ton universal testing machine boasts a computerized servo-controller that allows the machine to be used in a variety of testing applications. The system may be used for medium-cycle fatigue testing, load control, strain control, and displacement control. The open architecture of the state of the art MTS controller allows the machine to follow complex logic-driven test procedures. The hydraulicly driven crosshead allows the machine to be reconfigured for various tests within minutes.

Detail of Oven for 220K Machine

The multi-manifold control system allows a 110 kip (500 kN) secondary actuator to be used independently as well as in conjunction with the primary actuator. The secondary actuator can be mounted to the test floor of the laboratory as well as to a reaction frame for transverse/biaxial loading of specimens in the main MTS load frame.
