I have a question regarding the simulation of cone penetration tests using the SANISAND04 model. I have observed that the parameter m (yield surface size）has a significant impact on the penetration force, even m ranges from 0.01 to 0.03. The FEM simulation shows that the penetration force increases with decrease of m. What is the cause of this issue?

is it a drained or undrained simulation?
Thanks for your reply. It is drained simulation.
I’m not very familiar with the SANISAND model, but I would expect the forces to increase as the initial yield surfaces gets larger, since my elastic space also becomes larger. Maybe it’s somehow oversimplied my analysis. Does a decreasing m parameter lead to a smaller yield surface?
Thank you. The yield surface becomes smaller with decreasing m. The simulation result is very strange.
Hello. Any update on the results or potential cause for this behavior?
Hi, dear zhanng
did you complete the simulation in ABAQUS or in PLAXIS?
Hi,Dr Liu,
Have you solved it? Can I communicate with you on wechat?
No I havent solve this problem,
I can connect with you in Wechat
but how to find you on that?
