hi,
I have a research project on the buckling behaviuor of pipe piles (combined walls). My question is how to model the pipe-soil contact in an easy and efficiant way in ABAQUS (FEM). Thinking about Winkler spring.. that at first leads me to the asumption of the winkler spring subgrade modulus, which I obtain how - or asuume as?
Second, if I simulated the soil with springs - I have to conver the pile with springs (applying them at nodes). What do I do if a have a irregular mesh and how can I then calculate the correspoding spring stiffness?
thanks for help,
Anton
