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)

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...
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
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'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
