Residual stress - Ansys welding simulation

Click For Summary
SUMMARY

The forum discussion centers on the challenges of simulating residual stresses from TIG welding using ANSYS 12.0. Users report successful thermal analysis but face difficulties transitioning to structural analysis. Key solutions include creating a second model with structural elements, utilizing the LDREAD command to import thermal solutions, and applying boundary conditions before solving. The discussion highlights the need for clarity in moving from thermal to structural simulations in ANSYS.

PREREQUISITES
  • Understanding of ANSYS 12.0 software
  • Familiarity with thermal and structural analysis concepts
  • Knowledge of APDL (ANSYS Parametric Design Language)
  • Basic principles of TIG welding and its effects on materials
NEXT STEPS
  • Learn how to use the LDREAD command in ANSYS for importing thermal data
  • Explore structural modeling techniques in ANSYS APDL
  • Research boundary condition application in ANSYS simulations
  • Study the principles of residual stress analysis in welding simulations
USEFUL FOR

This discussion is beneficial for mechanical engineers, simulation specialists, and researchers focused on welding processes and residual stress analysis using ANSYS software.

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...
