Handling Element Distortion Errors in Hyperelastic Material Models Using Ansys Mechanical - Lesson 3
Ғылым және технология
Hyperelastic materials such as rubbers are used in a variety of engineering applications for sealing and other purposes. In many of these applications, the components made of hyperelastic materials experience large strains, and modeling such cases often involves accounting for geometric, material and contact nonlinearities. Due to these reasons, we often encounter the excessive element distortion error when using hyperelastic materials in our simulation. In this video, we will discuss why element distortion errors occur and learn how to understand various error messages and use them to diagnose and fix the underlying issues.

This video solved my issues!!! Thank you so very much. Your channel has been incredibly helpful!
As another suggestion you could also consider using mixed u-P formulations and uniform reduced integration, these can be adjusted by using KEYOPTS options for each geometry.
Thank you very much. The information were really helpful.
This has been super helpful and very well presented :)))
very well explained! thanks
Nice explanation. Thank you.
Thank you. It was very useful to me.
Thank you, great explanation ;)
Lovely explanation
thank you
nice video, however, load increament in larger substeps increased my solution time. Nonlinear mechanical of mesh behaviour also increased solution time. Please suggest.
Good
Hi, how I could know the correct selection of initial substep, minimum and maximum
which all test data do I need for hyperelastic model (by ArrudaBoyce or Ogden) to simulate indentation on rubber?
I am honestly not a fan of these AIS stuff. For one, for the same number of minutes, you can present information in a much denser form. Just look at the CAE associates videos from a decade ago (now part of Ansys), for the same number of minutes, they presented so much more information. The amount of information presented in this video could have been summarized in 5 slides and presented in just a few minutes. The 2nd major problem is the presentation style, having this talking head is just so distracting. Like, I honestly don't know what it accomplishes. What if you hide the talking head, and just have someone speak, would that really remove any value from this video? What does adding a talking head really accomplish for people who try to learn?
