"Composite material damping" specified in the materialproperties assigns the value of damping ratio for the material. Itisn't the damping coefficient, "c" that is in all the structuraldynamics books. It means I can get whatever response I want out ofthe simulation as opposed to a simulation of real life response.
dampingshould depend on the mass and stiffness of the system in the formof damping = 1/root(k*m) for a single degree of freedom. So if Iuse a heavier mass, the response at resonance should increase
due to damping decreasing. That doesn't happen unless I also cheatby decreasing DAMP when I increase density.
Without cheating,
response turns out to be invariant with mass which isn't what Imeasure experimentally.
Uh...so now what? Cheating is fun but then the lightning strikesand I smell bad after.SolidworksSimulation
