Pressure Dependent material

[Pedro Montenegro]

Dear users:

I'm starting to model a soil-structure interaction problem and i'm thinking on using the PressureDependent modelo for the soil.
I'd already read something about this model but i still dont have enough literuture about it. Can any one say me where i can find some papers which explains the main topics of this constitutive model and how i can calibrate it with lab tests? (which tests i should do, how can i get the parameters, etc).

Best Regards

Hi,

There is a paper in EJGE called 'Free field analysis of liquefiable soils' by Y. Chen, X. Liu and H. Dai.
This gives a method to calculate the liquefaction parameters based on field and lab testing.
I found this on the Auckland University databases but you might be able to get it online or off your own university databases.
