Soil Modelling Parameters

Soil Modelling Parameters

Hello all,

I am trying to model the interaction of a pneumatic tyre rolling on a deformable soil. Any type of deformable soil (sand-mud-muskeg).

Although I have managed to make a somehow reliable and realistic model regarding the rolling process of the pneumatic tyre, I am facing significant errors and troubles with choosing the material parameters of the soil.

Most of the researches in my field are modelling the soil using Drucker-Prager or Mohr-Coulomb. However, there is a lack of a full D-P criterion parameters description in almost every publication.

So my question is:

Is there any chance any of you might have some valid soil material parameters using the D-P yield criterion for any type of soil?

Thank you very much for any reply.

If you haven't already, try the US Army Corps of Engineers Engineering Research and Design Center (formerly Waterways Experiment Station). They have done a lot of research on vehicle mobility on soft ground, and some of it may be unclassified and available.

For most of us practicing geotechs, Drucker-Prager is a distant memory from grad school. I remember the name, but no more than that.

I have already tried WES but there are many parameters missing in order to complete a Drucker-Prager model in Abaqus.

Thank you for your time.

You might want to ask in the Agriculture Engineering forum and check out Ag Engineering sites - they have to worry about equipment loads for farming - how soon on "soft" soil can they get on to get the crop in - or out!

Thank you very much for your reply. I will try so
