Shear Fatigue Tester For Testing Lab Workshop.
Shear Fatigue Tester - For Testing Lab
The ability of polyurethane foam slabs to withstand the effect of repeated compressions is determined with the help of a Shear Fatigue Test.
In this test, a test specimen in shape of a square block is held over a flat reciprocating platform and is pressed down from top by a horizontal cylindrical roller inclined at an angle of 15° to the direction of motion of the platform. The platform is moved for a specified number of cycles and the effect of repeated compressions produced on the test specimen is evaluated by finding the change in its thickness and indentation hardness number.
