MIL-810 drop test, values in Simulation for plywood impact surface

Question asked by Bert Bourgeois on Jul 20, 2015



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.
