Re: soil property in ABAQUS?

Sorry, I can't understand what do you mean by attenuation parameters.
You have to choose first which constitutive model you want to use. Abaqus has Mohr-Coulumb and Drucker Brager. Usually I prefere to use Mohr-Coulumb.
 
Hope that help you

Hi,
I am trying to simulate soil material (stiff clay & dense sand) in ABAQUS. I
searched online and got some parameters, such as density, young's modulus,
and poisson's ratio. I know attenuation is a major property for soil
material. However I was not sure whether I should use Rayleigh damping or
viscoelastic property. Anyone has experiences of simulating soil material in
ABAQUS? I would really appreciate if you could tell me where to obtain or
how to calculate those attenuation parameters. Thanks a lot!

Jerry
