Any database for Duncan-Chang parameters range?
Any database for Duncan-Chang parameters range?
(OP)
Hello.
I'm looking for a database of Duncan-Chang(hyperbolic) model parameters range, for the materials used in rockfill dams.
Any idea where I can find such thing?
Thanks in advance.

in addition I send you paper, where you could find what are the rough values that are used for the soil materials. I suggest you to make several triaxial tests for the materials before you adopt any value for the parameters.
Cheers, Done
