Constant Displacement Foam Fatigue

The Constant Displacement Foam Fatigue is a floor standing instrument with four daylight sample areas, two on the left and two on the right side of the machine.
The compression platens for samples measure 500 mm x 500 mm.
The center, top and bottom plates are stationary, while the upper and below center platens simultaneously move up and down, adjusted to the percentage of compression required via an adjustable cam.
Samples would be compressed between 4 compression areas for the relevant amount of time set on a cycle counter. Holding the samples in place would be via double sided tape.
