Hi,
This is stress singualrity phenomena and not stress stiffening effect.
Just do stress singularity search and find threads related to this topic.

Hai,
I have the numerically simulated results before proceeding for experimentation.So, I have complete description of mode shapes. I attached the accelerometer and excitation in the maximum response region(anti-node in modal sense).
I carried out modal analysis of one of the body with...
Hai,
Thanks Greg Locock.
1) I will explore the effect of stress singularity on simpler model.
2)The structure under consideration is having first natural frequency of 750Hz. I think deviation of 5Hz is insignificant.
3)The actual model consists two sheet metal structures welded together...

Mesh convergence-structural analysis
Increase the number of elements gradually. Then plot the stress or dispalcement(field variable) of some reference point in critical portions of your model against the number of elements. The point at which the there is no change in field...
Hai,
What is the file format your exporting? whether it is iges.
In preprocessor we can set the units. But setting the units has no meaning in ansys? If your exported model in CGS and then try to import it in SI units in ANSYS. ANSYS wouldn't do the job of putting the scale factor. You have to...
