The equipment is used for the characterization of deformation processes of metallic materials under very high cycle fatigue loading and extreme environments. The frame is a Very High Cycle Fatigue (VHCF) testing machine designed to test specimen at 20 kHz. It allows mechanical characterization of materials up to 109 or 1010 cycles in the gigacycle regime. The frame can be used in fully-reversed mode or for non-zero mean stress testing at cryogenic, room, and high temperatures.
