I figured out a solution eventually, I'm sort of surprised no one else could offer it as it was very simple. The easiest way to do this is to simply make multiple parts (concentric spherical shells - not shell element type - in my case), combine them together while preserving the boundaries and...

Can anyone please explain step by step how to do this? I gave up on this a while ago but now need to do it again. I want to create a sphere with a spherical hole in the middle (I know how to do this easily by "Create new part --> 3D Deformable Solid Revolution --> Draw half a sphere with another...

I agree with both gugi91 and cooken, but there are pros and cons to both: If you follow gugi91's method, and you use a frequency of 1 in your input file, you will get every stress value calculated by Abaqus for a certain number of elements in your model. This will give you high frequency data...

Would you like to view stresses at a particular node/element? Or would you like to see a color map cross-section of your model with colors representing the values of a given stress component? To do the latter, create a view cut and specify the plane, cylinder, sphere or isosurface you'd like to...

Thanks for the reply rstupplebeen! I haven't looked at the attached CAE file yet because I am not at my main computer. Do you know if your mesh would work with Abaqus Explicit? Would you mind attaching your .rpy file so I can try to follow the same procedure for a sphere? Thanks again! - rogersma

I believe it is the first principal stress at which your material would fail. You could try using the stress from your tensile stress-strain data, assuming your data is given in engineering units, by noting the last point of the stress-strain curve where the derivative changes sign. More info here

Hi Chen1, I would say that if you do not see a sudden change in stress state, then there isn't really much to diagnose here and it seems that your simulation isn't reaching a failure point. In general, a dynamic failure ("violent failure") is characterized by a sudden change in stress state...

Hi corus, Would you mind explaining how to partition the spherical sketch in 2D? Is it some sort of view option? I haven't done much meshing in the past year as I've been altering my VUMAT to match theoretical and experimental results for simple 2D geometries. If you could briefly outline how...

Hi all, I have been using Abaqus for ~1 year, mostly for 2D simulations (plane stress) but have recently started using 3D meshes. My problem is fairly simple, and hopefully someone can answer it. My model geometry is a solid sphere with a spherical hole (easy enough to create using the...
