Great tutorial... didn't skip any steps.. in my consulting business I frequently create "how-to" videos using various software programs... and as an adjunct professor at CSULB I always explain every step and don't assume my students will automatically just know what I meant instead of what I said.
Thanks Bryan. Your book was available in my university library ( Staffordshire uni in UK) and I have used it religiously and referenced it on my masters module of structural analysis. It has been quite helpful.
@@cadinsider964 It certainly can be modelling asymmetrically but a 2D plane either assumes plane stress (with zero stress through the plane) or plane strain (with zero strain through the plane) - neither of these would be correct if you just took a slice through a stepped bar loaded axially.
How can i simulate 2D axisymmetric model with a force isn't symmetric ? It means the force just has the impact in one side of the model (don't be axisymmetric)
Yes, you are correct. In order to use axisymmetry (or indeed any other type of symmetry) both the geometry and loads must be symmetric about the axis of symmetry.
ANSYS Classic/APDL has a method called "harmonic axisymmetric" that allows you to apply non-axisymmetric loads to a standard looking axisymmetric model. The element formulation is adjusted to allow this behavior. The term harmonic is confusing to many because the harmonic refers to Fourier coefficients used to define the non-symmetric loads. Harmonic here does not mean dynamic or time-changing.

Glad it was helpful!

Hi Kyle, thanks for your kind comments - I'm really glad the book was of help to you!
thanks for detailed explanation..very helpful
Glad it was helpful!
can we model stepped bar as u moddelled in 2D plane as if is it a plane cross it along the length?
Hello, I am sorry but I don't understand your question. Can you rephrase it?
@@LearnFiniteElementAnalysis I mean if the there is a stepped bar loaded axially. can it be modelled axisymetricaly and as a 2D plane?

How to expand axisymmetry result.
Thanks. Very usefull.

Symmetry should be not only in geometry but also in loading. Keeping this in mind you can try make a symmetric model if possible.

Very lucid video.
