Hi everyone:
Now i am doing a dynamic analysis of a sandwich structure in ABAQUS
,which is consist of viscoelastic (ER) material and elastic ones. I want to
input viscoelastic material parameters by means of Frequency=formula.But
I have only formula of shear modulus(including storage modulus and
loss modulus expressed in frequency domain) about the material
,Real(G)=G',Loss
factor=G'',(G=G'+iG'').So how can i
get the paraments required by Frequency=Formula? Thank you and waiting
for your answer!
