First time poster.....

1. I want to use drop test to simulate a 'transit drop test' according to the MIL-810 std.

The std state dropping from 1220mm onto 2inches of plywood (plywood which sits on a concrete floor)

But I am having trouble sourcing what the help refers to as 'normal stiffness' and 'tangential stiffness' for plywood.

Are those K values? or known as something else?

2. should I use a value for the Contact Damping at all?

Thanks a lot in advance.
