Ogden Material -> Yeoh, Neo Hookean, Mooney Riv.

Hi!

I wanted to ask how I have to choose the parameters to get the Yeoh and the Neo Hookean material using Law 42 in Radioss:

For Mooney Rivlin it is explained in the documentation:

a1 = 2, a2 = -2, mue1 = 2, mue2 = -2

How is it for the Yeoh and for the Neo Hookean?

Best, J

Please use LAW 94 for Yeoh.

Using LAW42, The Mooney Rivlin parameters C10 and C01 can be used to calculate mu and alpha,

mu1=2*C10

mu2=-2*C01

alpha1=2

alpha2=-2

For Neo-Hooken use.

mu1=2*C10

mu2=0.0

alpha1=2

alpha2=0.0

Last as suggested by Prakash for Yeoh use LAW94 which was added in RADIOSS 2017.2.

Thanks,

Andy
