Friction stir welding simulation in abaqus using Coupled Eulerian Lagrangian CEL method Part 3 of 3

[@amolwable5469]

Thank-you for explanation and uploading the video. In my case I followed all steps but after submit, program runs till 1 step (i.e. plunging) and does not moved to step 2 (i.e dwelling). Please suggest what to do. Does it take longer time from step 1 to step 2.

[@Abaqus-Tutorials]

is a step 1 finished?

[@ActuConnect24]

Tell me sir, is it possible to add other interactions such as for example sliding and rolling friction as well as heat flow due to viscosity. above all tell me how to apply them, can we apply them to the plate directly or we must apply them to the Eleurian body.

[@Abaqus-Tutorials]

Yes we can

[@panagiotisraptis8005]

Hello and thanks for the tutorial. Could you please tell how much computational time is needed to do the full analysis?

[@Abaqus-Tutorials]

not more than 45hr

[@sahilgupta9675]

Really depends upon pc specifications and hardware

[@Ahimsa-Channel]

Many thank to FE Support-Abaqus. Your videos are very helpful for my project. I have some question to ask you about my result. In my case, the result doesn't show the deformation. Do you have any suggestion about my problem? Thanks, TP

[@Abaqus-Tutorials]

It may have many reasons, like insufficient load, material property, ...

[@collectt]

Sir, how long does it take to complete running? It's been three days for me already

[@avezshaikh4502]

Really? I have been waiting since 2 hours, I had this question to keep the computation going should I keep the desktop on or if the pc shuts down, would the computation stop?

[@collectt]

@@avezshaikh4502 no

It will ask whether you like to restore.

[@filippocosta9662]

video is very useful. presentation is clear. could you upload on KZbin a fsw simulation with lagrangian eulerian arbitrary method ? thanks a lot.

[@neeruchaudhary2982]

Hello sir I have a question.....when doing friction stir spot welding fssw then both of the whole workpieces will be made eulerian or some part of them

[@NoName-qt2ly]

I also have same question. Please tell if you got answer for it

[@gabrielaguirre6447]

Didn't you mesh the wp and assign the section?

[@Abaqus-Tutorials]

Yes, that is correct

[@DanielRamirez-ls1ff]

Hello! Did you use some type of mass scaling to reduce the computational time?

[@Abaqus-Tutorials]

I didn't use, but you can use if you need

[@dohuynhnhu]

Hi Sir, Do you used the material alloy 6061 - T6? Specific heat of 6064 - T6 is ~ 900 J/(kg.K), but you chose it is 67000 in the 1st part. I want to know the unit that. Can you answer my question, please?

[@marutidhobale3075]

Sir are we getting residual stresses from this analysis directly ?

[@Abaqus-Tutorials]

possible!

Hello sir i followed every step and in data check i getting output not available for element type ec3d8rt

Hi sir, I did the same process but I am getting excessive distortion again and again.Can you please help.I tried aplying ALE as well but still same issue. in visualization, it is showing some erratic distortion at tool work interface.

[@Abaqus-Tutorials]

At what step this happened?

[@NoName-qt2ly]

@@Abaqus-Tutorials Initially it happened in first iteration itself. But later on when I increased the size of eulerian part. It happened in welding phase

[@arindambaruah5419]

Thankyou for sharing the helpful tutorial. While performing the simulation as per your video, in the first step, an excessive node rotation error is observed. Could you or anyone in the comment section kindly help out with the problem ?

[@Abaqus-Tutorials]

Try by lowering mesh size

[@ayodelayakinpeloummy880]

Pls in visualization, the tool is translating in space instead of translating from one end of the workpiece to another, pls I need help

[@Abaqus-Tutorials]

be sure in boundary condition, especially download velocity

[@ayodelayakinpeloummy880]

@@Abaqus-Tutorials yeah,I figured that out already but I am not still seeing result, the temperature contour is not corresponding to your work and it is had to plot the temperature graph,if you could help with this, I would be grateful. Thank you Sir

[@Abaqus-Tutorials]

@@ayodelayakinpeloummy880 It doesn't matter the temperature variation as long as you followed all steps correctly.

[@ayodelayakinpeloummy880]

@@Abaqus-Tutorials Thank you Sir for your response Sir, maybe I am not putting the problem in right word,the temperature is linear horizontally, instead of sinusoidal or something like that and the maximum temperature displayed is the room temperature and not the melting temperature Sir, I think the issue volume of fraction but I am not sure Sir

[@eshwarchintu9915]

I followed each and every step exactly, but I'm not getting the temperatures, it's just showing the initial temperature. Is there something that is to be done which isn't available in the videos ?

[@Abaqus-Tutorials]

In Interaction module, Interaction property manager>>>edit contact property, check heat generation in Thermal tab

[@sahilgupta9675]

Is possible to do this simulation on ANSYS with convince?

[@Abaqus-Tutorials]

Yes, defintely

[@akshittyagi5267]

Hey, did you do it on ansys? Actually i am also aiming to do that.

[@teklebirhanfisseha4934]

It is a very good scientific tutorial.However, why do you specify or limit the temperature in the counterplot options? this will not yield true temperature history. for example, if you want to plot the temperature after specifying the temperature to a certain value, the graph shows that some points on the graph are shown missing indicated by an arrow. So this could make the work unrealistic. isn't it?

[@Abaqus-Tutorials]

No, What I had done by specifying limit the temperature is changing the contour color. If you see carefully, @3:57 the maximum temperature was 599 but in reality there is no pure red color on the workpiece. So that the maximum temperature is obviously below 599. The maximum temp on workpiece was orange color that is around 431. If we limit the value to 431, the orange will change to red, this does not affect the result. The only purpose of limit the temperature is visualization. I HOPE YOU UNDERSTAND!

[@abhilashsharantambak91]

@@Abaqus-Tutorials yes it is going but time increment is very slow, how can I increase it without effecting on our response. Thank you for your reply sir.

[@NoName-qt2ly]

There is only one way and that is to coarsen the mesh.

[@NoName-qt2ly]

Halving mesh size reduces the simulation time by factor of 10.If you are reaching welding phase then please help me with excessive distortion.

Do the same by modifying material properties and boundary condition depend on the nature of your problem definition
