welding residual stress ansys tutorial
Dear Sir:

I am facing problem in welding simulation in ANSYS.

I have been doing sequential coupled thermo-mechanical analysis in Ansys.

I have done the transient thermal analysis and got the correct temperature distribution.

However, i am facing a problem in calculating the residual stresses.

I would be extremely thankful, if you would forward me simple tutorial for calculating

residual stresses during welding in ansys using sequential coupled thermo-mechanical analysis.

Best Regards

Welded connections are often the initiation sites of failure. Welds can contain sharp section changes, local discontinuities, high tensile residual stresses, and relatively low fatigue strength. The primary failure mechanism in welds is fatigue caused by propagation of cracks that are present from the welding process. The method of modeling welds in a structural analysis is critical for predicting the structural response and subsequent life.

This 30 minute e-Learning session demonstrates approaches to modeling welded connections in ANSYS.

Topics Covered:

Review of weld geometry and terminology.
Description of finite element methods for calculating the critical stresses in welds.
Review of approaches for fatigue analysis of welds.
