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 aim to calculate the tensile capacity of a pile after a cycle of lateral loading and unloading in Plaxis 3D. When I compare the post-lateral-loading axial capacity (Q1) with the axial capacity with no prior lateral loading (Q_ref), I observe that Q1…

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…

Hey everyone, I want to ask about transformation of curves from dynamic time to frequency domain in plaxis 3D because I need it to calculate impedance functions ??

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…

Hi All, Is there a way to extract the mobilized stiffness when using the Hardening Soil Model (or HSS)? I am interested in a numeric value (and not a symbol). Thanks

Hello All, I have a question about the hardening soil model. In PLAXIS we have HS and HSsmall for modeling soil behavior. In HSsmall, there is a parameter gamaa_07 to incorporate dynamic behavior which is not included in HS. Also, in the materials…

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…

Hello, Please, i'm BELOUAD Rabah, student in M2 Geosciences of energy at Paris Cergy University. I'd like use Plaxis to design the anchor pile of floating windfarm for my master thesis but i didn't use it before, if someone could help me in this…

We are doing independent check / PE review of an deep excavation project, which majority of the excavation are in Rocks. The designer used Hardening soil model to model the Rock layers. My questions are: 1. is it proper to use HS model to model the…

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?

Hi, I was trying to model a tunnel problem using HSS, so I decided to check the Eur adopted by the program before performing the analysis. I found out that the values utilized are quite high in the initial stages of model and they are not matching with…
