Hi everyone, I’m trying to simulate a triaxial test by using Matlab, adopting the sand hypoplasticity model with strain softening but so far couldn’t succeed. Would anyone help me with such Matlab m.file. Thanks in advance.

Hi Ala,
You did not give us enough information on what you need.
So you try to build your own element test driver in matlab with hypoplasticity, right?
We do not know whether
(you have functional driver, but you have problem in hypoplasticity implementation)
OR
(you have functional driver and hypoplasticity implementation, but triaxial test simulation does not work)
OR
(you have nothing)
Let us know,
David
Thank you dear David for your prompt response. Yes, I’m trying to build a Matlab m file implementing the hypoplasticity constitutive relation to simulate an element triaxial test but I’m not professional neither in Matlab or in Hypoplasticity. My problem is the implementation the hypoplasticity tensorial equations in Matlab, especially when strain softening is considered. I am looking for a sample m.file in this respect.
I see,
So please check the following driver:

Dear David, I’m afraid that the link you sent doesn’t work!! I received the following message when I tried to download:
“Sorry! Download is not available yet.”
Best regards.
Ala
I see, it should be OK now.
Thank you so much dear David, I’ll try to figure out what is going on, although it is not (simple), at least for me!!
Best regards.
