Don’t hesitate to ask any questions you might have about the explanations presented in this video using the comments below. We try to answer all questions regarding the video details in the comments below.
Welding simulation of a lap joint is conducted according to a paper using the DFLUX subroutine.
In the second stage, cooling is simulated via defining the forced convection and radiation.
In the third stage, tensile test is simulated.
All of the mentioned stages are simulated in a multi-step analysis.
Each stage is included in a step.
In stages 1 and 2, fully coupled analysis is conducted.
To simulate the melted zone, the USDFLD subroutine is used.
Laser beam is modeled as a moving volumetric heat flux.
Three premium packages are available:
Package 1 is the complete package. If you have your own DFLUX and USDFLD subroutines, you can purchase package 2 instead of package 1. Also if you only want to have the subroutines, you can purchase package 3.
Package 1 description:
- cost: 25 EUR (must be paid by the PayPal or other payment methods according to your country)
- included files: Abaqus files (CAE, JNL and INP files), subroutine file, the reference paper, a complementary video (to explain the written subroutines in detail)
- models are created by using Abaqus 2014
- level: advanced
Package 2 description:
- cost: 17 EUR (must be paid by the PayPal or other payment methods according to your country)
- included files: Abaqus files (CAE, JNL and INP files), subroutine file, the reference paper

Thank you Amirhossein for this video. but i have a question. you use a USDFLD and define density as field variable and you can predict melted zone. how can correlation between density and melt zone?

Hi. You are welcome. No I don't relate density to the melted zone. Both of them are dependent parameters. In such simulations, these parameters are dependent on temperature and I visualized the melted zone with respect to the temperature field. I used USDFLD subroutine to do this and used temperature field in this subroutine.
I don't understand how can you apply thermal simulation in Abaqus. Thank you so much.

Hi. We have several videos about the thermo-mechanical analysis via Abaqus in our KZread channel: First, please watch this video : kzread.info/dash/bejne/ZKKBo8SFY7O8htI.html Second, please watch this video : kzread.info/dash/bejne/aW1-yrOuZa2nn9Y.html Then you will find out what to do. If you had any questions about those video's content, you can ask it in the comments below each of them.
can you share the USDFLD subroutine (below the DFLUX main subroutine you showed at 11:30 ) which is related to the visualization FV1 (melted zone) ?

Hi. The cost of the package including the CAE, JNL, INP and subroutine files is 25 EUR which must be paid by PayPal. Also I will send a read-me file containing some extra explanations for your better understanding of the modeling and how the subroutine works. So, all of your possible questions will be answered via reading the read-me file. To purchase the package, You can send an email to me : mirzabozorg71@gmail.com
Thank you for this training, it is awesome. Is it possible to take this approach for AM modelling?

Hi. You are welcome. Yes of course.
When we define DFLUX, what should we enter in the @10:56 magnitude tab ? Does it need to be 1
@FemexIran

Hi. Actually this value does not affect the heat flux value and it does not affect the simulation. You can enter every number which you want. I usually set it to 1.
Hello I'm running a CEL model of stir welding joint with dynamic,temp-displacement,Explicit steps. How can create a step for tensile test with Explicit simulation please because I can't do it like in the video ?
@FemexIran
Жыл бұрын
Hi. you must define a dynamic explicit step after the step of the welding. I mean at least your simulation must have two steps : step1 for doing the thermo-mechanical analysis. step 2 for doing the tensile test. in step 2, some of the boundary conditions of step 1 must be modified.

@@oumaimatrad1915 In your analysis, first the tool must penetrate into the workpiece and do the welding and go out of it. Then the boundary conditions of the workpiece must change in order to conduct the tensile test. It means that one side of the workpiece must be fixed and the other side must move.

@@oumaimatrad1915 It depends on the original test rig and the position of the fixtures. In the tensile test, usually one side is fixed and the other side is moved. If the boundary conditions of welding process are not the same, you must deactivate them in the tensile test step and use the mentioned boundary conditions.
