PDMS properties?

Hi
I am currently working on a Solid-Acoustic problem, where I would like to use the material PDMS (polydimethylsiloxane) in two regions. However, when I try to make a user defined material, by inserting the density (965 kg/m3), Poisson's Ratio (0.5) and Young's Modulus (0,98 MPa), I cannot solve the problem. If I however choose another solid it solves it in no time.
Do any of you know, if a PDMS material has been made and can be imported? Or do you know which material constant I need?
Regards
Kasper

Hi
try poisson 00.495.
AS 0.5 is REALLY too much ;),
but normally you ave better material models for large nu materials, take a look at the doc

Good luck
