Residual stress - Ansys welding simulation

AI Thread Summary
The discussion focuses on challenges faced in simulating residual stresses from TIG welding using ANSYS software. Users report difficulties transitioning from thermal analysis to structural analysis, particularly in loading temperature history for further analysis. Suggestions include creating a separate model with structural elements and using the LDREAD command to import thermal solutions. Additionally, there are inquiries about conducting TIG welding analysis in ANSYS Workbench and moving the heat source during transient thermal analysis. Overall, the thread highlights common issues and solutions related to welding simulations in ANSYS.

Hello, first of all I apologize if there is already a topic with this solution but this is my first time here, and I'm a little lost :frown:

I'm developing a work which consists in the determination of residual stresses due to TIG welding. I have developed the model and ran a successful thermal analysis, however I am having trouble in moving to a structural analysis. I've read a few scripts but I can not load the temperature history for further structural analysis. The software I'm using is the ANSYS 12.0.

Thank you for your attention.

(I apologize for any mistake of vocabulary)
 
Engineering news on Phys.org
do you get the solution of your above mention problem?
Even I am working on simulation of friction stir welding in ansys and facing similar problem in getting result for residual stresses induced due to welding
 
If you are using APDL then what you have to do is:

1. Create a second model that has structural elements. (Just change the element type and recreate the model, if you are using APDL this is very easy.)
2. Use the LDREAD command to import the thermal solution onto the structural elements
3. Apply any additional boundary conditions
4. Solve and post process.
 
Hi i try to learn ansys workbench, i want to develop tig welding analysis in ansys workbench but i can not. i try yo do transient thermal analysis but i can't move the heat source(tig welding). Can you help me? Thanks...
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
