I want to plot 3d-yield surface of a modified cam clay model in octahedral plane like in the following links (any co-operation will be appreciated):

Mac computers come with a nifty application called grapher. I have seen similar software in Linux (http://k3dsurf.sourceforge.net/). You can create those kind of graphs in a jiffy using these tools.
MCC model in octahedral plane is simply a circle!
If you just want to plot an ellipsoid in 3D you can use Autocad or any other graphical software (e.g. Corel). I have made it in Corel.
Hi All,
Thank You very much for all of Your co-operations.
@ Krzysztof Sternik, I know that MCC model plot in octahedral plane should be circular and in p-q plane my surface is satisfactory.However, in octahedral plane it is not circular. I have attached my calculation steps. Can You kindly have a look the attached calculation?
Now I see that you are using a modified version of MCC that depends on Lode angle. More realistic - I would say.
Anyway, perhaps Matlab or Scilab (open source!) might be a good choice.
Hi All,
At last I have plotted 3d yield surface in Matlab. Thanks all for Your suggestions.
I have developed elastic-viscoplastic models:two surfaces (associated flow rule) and three surfaces (non-associated flow rule). I am highly interested to present my bounding surface according to attached papers Figures 3(page:2879). In Matlab using "hold on" I can plot two or three surfaces. I am wondering, can You suggest how to cut them along hydrostatic line so that image surfaces like attached paper may visualize?
hi Mohammad，the pictures in the paer you attached are plotted by Mathematica not Matlab，at least author say so，cause I saw his blog，but the blog written in Chinese 。
Hi Young,
In my opinion Author was not co-operative to share how it was plotted. Therefore, I plotted them by myself using Matlab from my point of view. You can plot them by Matlab, Mathematica, Maple or even Gnuplot.
@Deat Shako Ahmed, Sorry, exactly what do you want to plot?

Hi all
Mohammad Islam the same problem occur with me, I need to plot Mohr-Coulomb and Kim & Lade envelope in pi-plane but still with difficults. The word and the xls shared by you is useful for me? Because I've seen them, but they are foccused on others failure criterion
I carried out 4 true triaxial and referent the stress paths OK plotting with qx and qz diagram. But I would like to compare my results with this criterion above mentioned
