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 doing a NATM Tunnel Analysis in Plaxis 3D, but when everything is finished and the calculations are given, it shows a problem in phase 01 like this. (Soil body seems to collapse. Please inspect Output results. [Error code: 101] ) What is the reason…

I am simulating the experimental data for a free field condition for 1-g shaking with applied harmonic loading. If I am running analysis with HS-small model for dry sand. It is showing error as Accuracy condition not reached in last step. [Error code…

Dear Sir How to put internal pressure inside a pipe. If we are going with that tunnel one then two circular vertical surfaces are created at the two ends of pipes which looks like pipe is closed. So how to remove those to circular vertical surfaces…

Dear Community, I am working on the dseign of monopiles under cyclic load. The most important thing for that to cater is strength and stiffness degradation. In the link below I attached there is a discussion regarding constitutive model i.e. UDCAM…

While using PM4 models the effective stress calculation should be based on vu undrained or by using biot effective stress calculations as Pore pressure measurements and liquefaction criteria are the major concern?

suppose I am using 25 kN/m3 of unit weight of concrete and the unit weight of soil is 19kN/m3 and modelling lining as a plate element. Should i subtract the unit weights and multiply with the thickness?

How to calculate dynamic earth pressure around a circular tunnel?

On Calibrating PM4 models, how to generate g/gmax vs strain graph and damping vs strain graph, using soil testing to adjust the secondary parameters.?

if using 'Drained' for Drainage type in General and using PM4Sand in Mechanical tab as user defined, no pore pressures are generated in dynamic phase. Should I use 'undrained A' even for sand type material when using PM4 sand?

Hello Everyone. I am working on a design of monopiles under cyclic loading condition. I am using UDCAM-S model. It is clearly mentioned that this model can be used in offshore structures that experience storm loadings. I am aware that using this…

The pore water pressure above the tunnel is observed to be positive under dynamic loading that results into negative ru, excess pore water pressure ratios. What could be the reason? kindly help me

On using PM4silt for clay and using Undrained A and for sandy soils (PM4sand) Undrained A.is it correct to use this combination while studying for liquefaction analysis?

Hi all, Let's say the soil is cut vertically and then provide any support after some days (not immediately). Are any ways to check in Plaxis how many days the soil can be vertical before failure (with the influence of soil arching etc) => no any consolidation…

Hi, Is there a way of restrict the failure slope that PLAXIS 2D give me? For example in an earth dam I want that my slip mass for a pseudostatic analysis starts in the crest, is there a way to do that? Thanks

I am applying input motion data at the base of the model with PGA as 0.349g, time = 34.96 sec. In PLAXIS I am using 40 sec and 4000 steps with subsets =1 as time step is of 0.01 sec. In the results it was observed (the node on the prescribed displacement…

Generally speaking, after the tail of the shield machine is completely passed, there will be continuous consolidation settlement on the surface, that is, the settlement value at the same point will gradually increase. However, in the case tutorial, I…

Why liquefied points are observed in soil while using advanced constitutive models PM4sand and PM4silts before seismic loading? The liquefied points were observed in static phase only

I am currently working on a liquefaction analysis using the PM4Silt and PM4Sand models for a layered soil model in PLAXIS 2D. However, I have encountered an issue where the liquefied points are observed in the static stage only before the dynamic analysis…

Good day members. Please, I need a help to understand these basic concepts regarding FEM. Almost when I read papers dealing with geotechnical modelling, I find the following terms related with FEM softwares/models: Model validation Model/Software…

Hello, I need to use the Plaxis script to get the result but I have this error (No module plxscripting) in the script! I did below steps: 1- Activated remote scripting server 2- Started SciTE editor 3- Included boilerplate below: from plxscripting. easy…

Hello, I modeled a pile using plates elements with custom propreties. what i want to know is : 1- is it possible to get the geometry of the pile (diameter, length) or we can get only coordinates and do the calculations from there 2- is it possible to…

Please , can any one help me how to model Accrapods or tetrapods in plaxis 2d ?

Am trying to model the effect of thermal loading on the backfill behind integral abutment by using Plaxis 2D. I modelled the concrete bridge deck as Linear Plate element and provide a prescribed displacement near the top of the abutment. The applied displacement…
