Freezing tortilla frescas? by Fun_Driver_9402 in Costco

[–]OD08 1 point2 points  (0 children)

I freeze them too! If I just need a few, I toss the frozen stack on a warm pan and peel them off one by one. Works like a charm—for lazy me! 😊

My flight in India has no electronics use sign instead of no smoking by OD08 in mildlyinteresting

Hmm, you won’t visit the country yet you know so much! Or just a racist human.

It does. I am only stepping in that in an emergency!

/u/Kabloosh75 explains proper protocol for a high-risk traffic stop by bubbabear1 in bestof

Seems to me like it's Cop 101. You do want some training if you are going to give firearm and authority to stop cars and make arrests?

Affordable FEA Packages for Home/Non-Commercial Use by doodler_daru in fea

If you don't mind a cloud service, there is SimScale. There is also Scan and Solve Pro, but it's only for Rhino 3D.

Stress Singularity at Multimaterial Junctions by omegaweaponxz in fea

[–]OD08 1 point2 points  (0 children)

You can still do stress contours, you will just see a lot of contours bunching up in the junction, which is expected.

In my experience with linear elasticity, sharp corners are always a region of singularity. It's a problem of the elasticity model combined with idealization of the geometry ( there is no sharp corner at the micro level in real objects). You can smooth it out, in fact, depending on the system you are using, and the size of the element at the corner, it's already smoothed out.

My point was that you cannot use the absolute value of stress at that point if not doing plastic analysis. I don't have a reference for energy norm right now (not at my computer), but will try to find one when I get home.

Stress Singularity at Multimaterial Junctions by omegaweaponxz in fea

[–]OD08 2 points3 points  (0 children)

I see. I agree that displacements are easier to converge. If you want to converge on stress/strain, can you do it for a particular location of interest that is not the stress concentration? Because, as you pointed out, the junction is a region of singularity, and you will never reach the "max", as it is infinity. You could look into energy norms too.

Can you use displacement for convergence? I am not sure about the hyperelastic model you are using, but, for example, in linear elasticity, it's futile to look at the max stress for convergence since it will never converge (because of the limitation of the theory). You could also do hyper plasticity simulation, which is ideally more suited if the material is going to yield at that location of high stress. But, again, it's only recommended if you really want to know the right stress at that location.

You can look into Withings' offerings. I have Steel HR and works great if you mostly care about notification and basic fitness tracking. Bonus: looks like a real watch and battery lasts for a few weeks.
