Normal / Tangential Stiffness - Drop Analysis

I am struggling to reproduce / determine the Normal Stiffnessand Tangential Stiffness values for a flexible floor in a droptest.

The 2007 Professional Training manual indicates values can bedetermined by analyzing a plate of like material under normal andshear loads. I have not been able to reproduce the values in thetutorial.

Any pointers on how to reproduce the values?

Thanks,
