Description
Fluctuating Tensile Tests – MEG 20 TT – New
The MEG 20 TT is a Very High Cycle Fatigue (VHCF) testing machine designed for fully reversed (load ratio R=-1) and tensile-tensile tests (0<R<1). It allows mechanical characterization of materials in gigacycle regime.
The MEG 20 TT machine is comprising of a testing frame and a separate control cabinet called “Grey Box”.
The testing frame can be placed on a table, or on a sturdy welded-construction pedestal. It has a built-in ultrasonic generator, which allows the specimen to be loaded at a frequency of 20kHz.
One billion cycles is reached in 14 hours only, reducing the necessary time to get Wöhler’s curve. And of course the occupation time of the machine, improving drastically the return on investment (ROI)!
