Hydraulic Load Frame
The MTS Model 810 Test Frame is used to precrack KIC compact tensile specimens and to perform KIC tests. Loads are applied with a hydraulic system. The load capacity is 100 kN. The machine is operated with an Instron 8500 controller.
During the KIC test, the 8500 system is governed by a computer through a GPIB (IEEE_488) interface. The specimen is pinned into the fixtures. A crack opening displacement (COD) gage is attached to monitor crack size. Load vs. COD data are plotted and recorded.
