Hi all, I am trying to recreate the stress-strain curves from the HSS formulation to have a better understanding about the calibration process. I am using the following formulation as displayed in the "Material Models" manual: Nevertheless, this…

I am very glad to write this post because last time I got a benchmark problem regarding embankment consolidation problem over PVD-treated soft soil " Comparison of Drainage Line Elements in PLAXIS 2D and 3D.....". After that, I successfully published…

Hi, PLAXIS team, I'm struggling to understand what the upper limit for material stiffness, i.e. E50 in Hardening Soil Model is? I am exploring different material models for a very low to low strength Siltstone (UCS = 1MPa, E50 = 300MPa) and I was thinking…

I want to ask when reviewing soil improvement using PVD, why is the result of the decrease in time using my plaxis 2D when 2 m spacing is faster than 1.5 m spacing and 1.5 m spacing is faster than 1 m spacing?shouldn't pvd spaced closer should be faster…

Hi, I am performing calculations in Plaxis 2D for a deep excavation and am using the Hardening soil model. However i want to set a clay layer to Undrained B as i dont want to overestimate the shear strength of the material. When i change it to undrained…

Dear all, When using “Triaxial test” of the “soiltest” option together with the hardening soil model in PLAXIS 2D, input the parameters as Figure 1 and get the parameter E50 from Figure 2 according to the definition in Figure 3, then it can be found…

Hi PLAXIS team, Reading from PLAXIS manual, I see the following and agree with it. "PLAXIS has options to deal with undrained behaviour in an effective stress analysis, the use of undrained shear strength (cu or Su) may be preferred over the use of…

Dear All I have oedometer test data providing einit, Cc, Cs and also Multistage CIU triaxial data from which I have obtained c' phi'. I am utilising the hardening soil model for settlement estimates of foundation loading. My question is, do I need…

Hi all, Anyone please explain about the POP , why this diagram differs with OCR and in which instance use POP? Can use both OCR and POP at the same time or any conditions are there? Thanks, Nitha.

Hi all, If anyone knows the stiffness correlation based on SPT N value, please share. and any correlations with stiffness also please share. Thanks.

In PLAXIS 2D, for undrained (B) conditions, there are two parameters that are not specified in the manuals. I have to determine the parameters from just one CPT. What do the S u,inc and y ref represent? And what is their relevance in this model?
