Load Deflection and Hysteresis

This test records the stepwise force during compression and release of materials of construction.

 

Why this test is needed

How a support surface deforms under load, and how it pushes back on the body of the occupant identifies “tissue protection.”
     

How this test is performed

A disk shaped indenter is applied in a stepwise loading and unloading to the support surface.
