"Composite material damping" specified in the material
properties assigns the value of damping ratio for the material. It
isn't the damping coefficient, "c" that is in all the structural
dynamics books. It means I can get whatever response I want out of
the simulation as opposed to a simulation of real life response.
should depend on the mass and stiffness of the system in the form
of damping = 1/root(k*m) for a single degree of freedom. So if I
use a heavier mass, the response at resonance should increase
due to damping decreasing. That doesn't happen unless I also cheat
by decreasing DAMP when I increase density.
response turns out to be invariant with mass which isn't what I
Uh...so now what? Cheating is fun but then the lightning strikes
and I smell bad after.
